Ultrasonic Pest Repellers

How Electronic Pest Repellers Claim to Work

These devices, which you plug into an outlet like a nightlight, are supposed to repel pests by emitting an irritating sound. The frequency of the ultrasonic sound waves they produce is too high for human ears to detect. But bugs and rodents, such as cockroaches, crickets, mice and rats, can hear this high-frequency sound.

The theory behind these devices is that the sound will make pests uncomfortable, disrupt their eating habits and cause them to leave the area—whether it’s your living room, basement, or garage.

But studies have shown mixed results.
Research Shows Ultrasonic Pest Repellers Are Ineffective

Researchers have tested these devices in controlled experiments to determine if they work according to theory. In lab tests, using powerful ultrasonic emitters, some pests were dramatically affected by the sound.

But in real-life situations, using store-bought devices, research has shown that ultrasonic pest repellers are inconsistent and ineffective.

The devices available from stores and online aren’t powerful enough to affect pests. Their range is too short and the sound waves they emit are too weak to effectively repel bugs or rodents.

In some cases, mice and rats simply stop reacting to the sound—after initially considering it a threat, they become accustomed to it. Other pests don’t show any reaction. Even if the devices did produce effects on bugs, their range is too limited to control an infestation of any size.
FTC Warning

In 2001, the FTC warned many manufacturers of these devices to change the claims of success they printed on the packaging because there was no scientific evidence to back it up. Today, they aren’t allowed to promise completely effective pest control because there’s no research proving that their products will work.

Though packaging and customer reviews still suggest some level of success, the fine print makes it clear that nothing is guaranteed.
Should You Use Ultrasonic Pest Repellents?

Unfortunately, these simple, clean pest control solutions don’t eliminate pest infestations. Some users have reported success but that result was probably due to one of the many other variables affecting pest populations.

Before spending money on these products, consider the lack of scientific evidence backing them up and the availability of other, time-tested options.
Are Ultrasonic Pest Repellers Safe?

The same factors that make these devices ineffective—weak sound and limited range—also make them perfectly safe for use around people. We can’t detect the noise and it is not harmful to our ears.

You should, however, consider the potential effects of ultrasound on your pets. Dogs and cats don’t seem to mind the sound, even though they can hear it. But if the ultrasound is strong enough for pests to hear, it might frighten or irritate hamsters, gerbils and other small pets—even if only temporarily.
Better Pest Control Solutions

Without conclusive evidence that ultrasonic and electronic pest repellers work, it’s better to avoid these products and choose pest control methods that have been proven effective, such as traps and baits.

Traps and baits are different implementations of the same idea. Traps are meant to attract pests to the bait and trap them while baits are poisonous and kill the pest after it eats it.

Simple baits, such as peanut butter, are very attractive to rodents, making these products much more successful than electronic devices.

You might think one or two pests around the house is a problem you can handle yourself. The truth is that seeing one or two pests often signals the presence of a larger infestation. It’s important to control pests as quickly and effectively as possible—the best way to do it is to call the professionals at Aptive.

Bidet Toilet Attachment vs Toilet Paper

After spending weeks testing bidet seats, or washlets—devices that squirt water at your bottom after you poop—I came to one main conclusion. Using a bidet to rinse fecal matter off with water feels better and cleaner than using toilet paper. But is it actually healthier?

Companies that sell bidets certainly capitalize on the idea that it is. According to the copy on bidet retailer Tushy’s website, the device “helps prevent gross butt syndrome,” which encompases “hemorrhoids, UTIs, general germy stank.” Bidet.org has a blog entry with a laundry list of further ailments that the devices can help, and Brondell—maker of the bidet toilet seat that we recommend as a budget option—claims that bidets can prevent urinary tract infections.

I fact checked these claims with Dr. John Swartzberg, a clinical professor emeritus at the University of California, Berkeley, who evaluated the peer-reviewed literature on bidets for an article in the Berkeley Wellness Letter. (I asked him how many people come to him for medical advice on using a bidet. “You are the first person,” he said.) Although there is some support for some of the claims, ultimately, you likely shouldn’t turn to a bidet to improve medical issues.

It seems logical that a bidet would make you cleaner than toilet paper. They certainly made me feel cleaner. But there’s no hard evidence, no peer-reviewed papers, and nothing that proves bidets actually reduce the amount of fecal matter on your bottom better than toilet paper alone, or make it any less germy, according to Dr. Swartzberg. I personally found that how clean you get will vary based on whether you use it in combination with toilet paper—I found myself using a couple squares to get totally clean after rinsing off with a bidet. Never fear: Your butt is probably fine with whatever level of microbes and poop it’s sporting now. We do not have some national health crisis in America where our butts are too dirty. “General germy stank” is not a real health problem. (Tushy’s publicist declined my interview requests.)

Your butt is probably fine with whatever level of microbes and poop it’s sporting now.

What is a problem is itchy buttholes. An estimated 1 to 5 percent of the population has “pruritus ani,” as the condition is called scientifically. If you have this problem, your first course of action is to find out if there is an underlying disease causing the itching (“talk to your doctor” is going to be a theme in this post), and to treat that. If there’s no cause to be found, the recommendation (as spelled out in this paper) is to avoid anything that can irritate the anus, like toilet paper. Therefore, cleaning with water after pooping, whether from a bidet or not, is a good idea. “When a bidet is used, it is better to use warm water and relatively low water pressure to avoid irritation of the anus,” the authors of the paper write. They also suggest blow drying the area with a blow-dryer, rather than wiping off water with paper—bidets can help here, too, as many have fans to dry your bottom, though they are not as strong as a blow-dryer. (Using the air-dryer function also might blow microbes from your bottom into the air, adding to what’s known as the “fecal cloud.” That sounds gross, but it’s probably not bad for your health—every time you flush a toilet after pooping, small particles of fecal matter become airborne, and you’re doing fine.)

It’s possible that bidets can help alleviate other medical problems, such as anal fissures, hemorrhoids, or constipation, but again, there’s not a lot of data to support that. One small study found that using a bidet can reduce the “anorectal pressure.” Twenty participants had catheters inserted in their bottoms and spent a minute using the bidet, at various water pressures. The pressures that their rectums exerted on the catheter was lower when they used the bidet than when they did not. Lower anorectal pressure could in turn be beneficial for treating medical problems, says Dr. Swartzberg; although it’s important to remember that the effects of bidets on these issues has not been studied directly. Also, there’s at least one report that suggests a bidet could have been the cause of an anal fissure.

It’s also important to not use a bidet on too high of a water pressure setting. Many bidets—including our top pick—have a setting that is strong enough to penetrate the anus. That’s too much, say the authors of the paper on anorectal pressure. “A high-pressure water jet flow should be avoided as it causes reflex contractions of the anal sphincters and might damage the mucosa and anal sphincter in the long term.” Dr. Swartzberg put it in more plain terms: “This is a horrible idea.”

Charcoal Bags to Remove Odors

As the name may suggest, bamboo charcoal bags are bags filled with absorbent and natural bamboo charcoal.

Bamboo charcoal has long since been used fuel in various Asian countries, including China and Japan, and is created when different materials are heated, but not burned, at specific temperatures (800 to 1200° C) over an extended period. Thanks to its organic composition and its plant-based origins, bamboo charcoal is considered environmentally friendly and poses no threat to the environment when used as an air purifier. It can also be used to filter and clean tap water for drinking.

When used as an air purifier, bamboo charcoal is typically packed in linen bags for easy storage and use. Bamboo charcoal bags come in a variety of shapes and sizes, so there’s no need to worry about not being able to benefit from them because of size or weight constraints.

Bamboo charcoal bags generally come with prefabricated holes for hanging, allowing them to be easily hung around the house. If you need a simple air purifier but space is a concern, smaller charcoal bags featuring hang holes are sure to get the job done.

BAMBOO CHARCOAL BAGS AS DEHUMIDIFIERS AND DEODORIZERS

Bamboo charcoal bags also serve as effective dehumidifiers and odor absorbers. If you have musty, old or wet shoes, a small bamboo charcoal deodorizer bag does a great job of eliminating bad smells.

Bamboo charcoal bags even act as moisture absorbers, meaning they’re great to hang around areas like closets which are prone to humidity and bad odors.  Bamboo charcoal is different to other air purifiers and charcoals on the market, and is approximately 10 times more absorbent than other, more common types of charcoal – making it an ideal air purifier, dehumidifier, and deodorizer to have around the house.

SAFE AND ORGANIC

Activated bamboo charcoal absorbs any moisture, including from fumes and gases, that passes through it. Since bamboo charcoal is organic, the absorption process is a natural one and no harmful chemical additives are used to mask odors – making it a safe and eco-friendly alternative to conventional chemical deodorizers.

This assures you that bamboo charcoal bags are environmentally friendly and safe to use around children and pets.

AN EFFECTIVE NATURAL FERTILIZER

Once the bamboo charcoal bag has been used up and is no longer effective, it can be used as a natural fertilizer for your garden. Simply cut open the charcoal bag and sprinkle its contents onto the soil. Bamboo charcoal helps plants absorb and nutrients from the soil much more effectively.

WHAT IS ACTIVATED CHARCOAL?

Contrary to popular belief, activated charcoal does not come from the same dangerous, chemical-filled briquettes commonly used for barbecue grills. In fact, activated charcoal comes from carbon-rich organic resources like peat, sawdust, coconut shells, and bamboo.

For this article, we will focus on the latter as the main source of activated charcoal. To produce activated carbon, bamboo that has grown for a minimum of five years is harvested and heated in ovens for a long time to produce large chunks of charcoal.

When making activated charcoal, the charcoal is ground to a fine powder which increases its surface area to over 600m2 per gram. Additionally, the volume of charcoal produced by bamboo allows for better absorption and these two factors combined make activated bamboo charcoal a more effective and efficient moisture and odor absorber when compared to other types of activated charcoal.

Because of this, bamboo charcoal is the ideal type of charcoal to be used in charcoal bags. What makes bamboo charcoal so effective at absorbing moisture and odors is the complex and rigorous Pyrolysis process it undergoes.

HOW ACTIVATED BAMBOO CHARCOAL IS MADE

Pyrolysis is the process of heating a source material (in this case, bamboo) to an extremely high temperature and charring it slowly, taking care not to burn it, until charcoal is produced. Following the heating process, the charcoal then goes through an activation process in which it is ground and treated then left to absorb oxygen over time. Thanks to the increase in oxygen, the charcoal becomes more permeable – which helps in the elimination of foul smells.

How to Stop My Dog From Barking

I have seen there are several questions on aggression on the forum, but I am specifically after methods to train away aggression caused by fear.

Our vizla male, Slater, has just turned 12 months. As we don’t yet have children, he has taken that on role like a champ – and I believe – given us a good year of training for when the first two-legged one arrives. I believe we have been through every stage of typical Vizsla puppy behaviour, including the early-teeth biting, three/four month obstinacy, the erratic bursts of cracy energy from 19pm to 22pm, the tearing down the wall paper, the eating the sofa phase, and the list goes on… It seems like as soon as we are celebrating one victory, Slater delights us with a new “phase”

Now we are starting to see the hormones kicking in. Slater has been a very well tempered dog, socializing fine with other dogs and with people. However, more recently he has had some bursts of aggression towards certain dogs and some people. In most cases the other dog may have barked first, and Slater completely looses it. I hold him on a very close leash and correct him, but I can only calm him down when he is led away from the other dog. Most recently, with my wife walking him, he started nibbing hard (biting but controlled) at my wife´s arm when she tried to constrain him. These sudden bursts of aggression / barking can also occur with some people; usually people wearing a motorbike helmets, carrying trolleys and sometimes homeless (living in Rio that is unfortunately a very real part of the landscape).

To me it seems like he goes nuts when he senses aggression or fear in another animal or person. I would like to understand how worried we should be and how to address this.

Our veterinary and our trainer is recommending to neuter him, but I would like to avoid that if this is a question of training.

Thanks in advance for insight and advice

Fixing Windows 10 The Easy Way

Fix – Corrupted system files Windows 10

Solution 1 – Use SFC tool

If you doubt that your system files are corrupted, you can fix them by using the SFC tool. This is a command line tool, and it will scan your PC and repair any corrupted system files. To start SFC tool, you need to follow these steps:

Press Windows Key + X to open Win + X menu and choose Command Prompt (Admin).
corrupted-system-files-cmd-1
When Command Prompt opens, enter sfc /scannow and press Enter.
The repair process will now start. Don’t close Command Prompt or interrupt the repair process. The repair process can take a while, so wait patiently while it completes.

After the repair process is finished, you’ll see Windows Resource Protection did not find any integrity violations message if your system files aren’t corrupted. However, SFC tool can’t always fix corrupted files, so keep that in mind.

If you want to view SFC log, you can do that as well. To do that, follow these steps:

Open Command Prompt as administrator.
Enter findstr /c:”[SR]” %windir%LogsCBSCBS.log >”%userprofile%Desktopsfclogs.txt” command and press Enter. By doing this, you’ll create a sfclogs.txt file on your Desktop.
Open the sfclogs.txt and check the results of SFC scan.

Keep in mind that this log file contains only information related to SFC scan that is performed in Windows.

Solution 2 – Use DISM tool

If you can’t run SFC tool or if SFC can’t fix the problem, you can try using DISM tool instead. DISM stands for Deployment Image & Servicing Management tool, and it’s used to fix any corruption problems that can prevent SFC tool from running. Just like SFC, DISM is a command line tool that is used to repair system files. To run it, you need to follow these steps:

Open Command Prompt as administrator.
Enter DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Repair process will now start. The repair process can take 10 minutes or more, so be patient and don’t interrupt it.
After DISM tool repairs your files, restart your PC.

When your PC restarts, you need to check if the problem is resolved. If the issue still persists, run SFC scan again.

But if you’re still having issues on your PC or you simply want to avoid them for the future, we recommend you to download this tool (100% safe and tested by us) to fix various PC problems, such ascorrupted files, malware and hardware failure.

Solution 3 – Run SFC scan from Safe Mode

Sometimes SFC scan can’t repair your files from Windows, but if that happens, you can try running SFC tool from Safe Mode. Safe Mode is a special mode that uses only default drivers and applications. By using Safe Mode you’ll eliminate any possible interference from third-party apps. To start Safe Mode on Windows 10, do the following:

Open the Start Menu.
Click the Power button.
Hold the Shift key and choose the Restart option.
You’ll see three options available. Select Troubleshoot.
Navigate to Advanced options > Startup Settings. Click the Restart button.
When your PC restarts, you’ll see a list of options. Select any version of Safe Mode by pressing the appropriate F key.

When Safe Mode starts, repeat the steps from Solution 1 to perform SFC scan.

Solution 4 – Perform SFC scan before Windows 10 starts

Sometimes you need to scan and repair protected system files, but you can’t do that from Windows 10. To scan protected system files you’ll have to run SFC scan before Windows 10 starts. To do that, follow these steps:

Restart your PC by following the first three steps from the previous solution.
When list of options appears, select Troubleshoot.
Choose Advanced options > Command Prompt.
When your PC restarts, you might be asked to enter your username and password, so be sure to do that.
Now you need to find the letter of your Windows 10 drive. To do that, enter wmic logicaldisk get deviceid, volumename, description command and press Enter to run it.
Pay attention to Volume Name. In most cases Windows Volume Name will be assigned to D letter. This is perfectly normal if you start Command Prompt before starting Windows, so no need to worry about it. In addition to checking the Windows drive, you should also check System Reserved drive. In most cases, it should be C.
Now enter sfc /scannow /offbootdir=C: /offwindir=D:Windows command and press Enter. Be sure to use the letters that you got from the previous step. In most cases, you should use C and D like we did in our example, but if for some reason you get different letters you should use them instead.
The scanning process will now start. Wait while your system files are scanned.
After the scan is completed, close Command Prompt and start Windows 10 normally.

Solution 5 – Replace the files manually

Sometimes in order to fix the problem with corrupted system files you need to replace them manually. This is an advanced process, and if you decide to perform it, we advise you to be extra cautious. First, you need to open your SFC log and check which corrupted files can’t be repaired. We already explained how to view SFC log file in Solution 1, so be sure to check it out for instructions.

After you find the corrupted file, you need to transfer a healthy version of that file from another PC to your PC. Keep in mind that both PCs have to use the same version of Windows 10. To replace the corrupted file manually, you need to do the following:

Fix Windows PC

Coincidental nerds can spare time and cash with these essential Windows PC investigating proposals.

The investigating tips gave here address fundamental, regularly ignored issues that don’t expect you to open your PC’s case, handle equipment segments, or dig further into Windows’ inward workings. Keep in mind that your objective here is to take care of a current issue, not make another one. On the off chance that you feel awkward playing out a specific activity, bring in somebody with more ability.

We center around investigating four basic situations that happen with Windows-based PCs.

The PC won’t control up.

The PC controls up, yet the screen is clear.

The PC won’t boot from the hard drive.

Windows won’t start up appropriately.

It would be ideal if you remember that these are on the whole nonexclusive suggestions. With the tremendous number of various makes and models of PCs out there, particular investigating steps may differ to some degree. On the off chance that these means neglect to address the issue you are experiencing, you should look for guidance from an expert or, if your PC is still under guarantee, from the producer.

To investigate your PC, take after the means in each area underneath all together.

The Computer Won’t Power Up

Is the PC’s energy rope connected immovably to a divider attachment or electrical extension, and is the electrical extension on? Provided that this is true, take a stab at stopping the PC or the electrical extension into another divider attachment. In like manner, watch that the power string is immovably associated with the PC’s energy supply outlet.

Is the power supply (the part on the PC to which the power line is joined) changed to the “on” position? Does the PC additionally have a voltage setting, and in the event that it does, did it get changed to an off base setting?

On the off chance that all the above falls flat, append a known working force string to the PC’s energy supply. Connect it to and endeavor to control on once more.

Unplug every single outer gadget from the PC, for example, printers and scanners, with the exception of the screen. On the off chance that the PC controls on without the gadgets, include the peripherals back each one in turn until the point when you can distinguish the issue gadget.

For PCs, notwithstanding the above, evacuate and reinsert the battery and power the gadget on without the string. Most workstation batteries have charge pointer lights. Squeezing them will make them illuminate and demonstrate how completely charged the battery is. On the off chance that the pointers don’t illuminate even after the PC has been connected to for some time, the battery should be supplanted. Substitutions can be gotten from the maker or online through outsider affiliates. In the event that you purchase from an online retailer, ensure that you affirm that the trade is for your particular PC display. PC batteries must fit every particular model precisely.

The Computer Powers Up, yet the Monitor Is Blank

Is the screen connected immovably to a working divider attachment or electrical extension, and is the electrical extension turned on? Assuming this is the case, have a go at stopping the screen or electrical extension into another divider attachment.

Is the screen’s energy catch changed to the “on” position?

Are the screen’s shine and difference controls legitimately balanced?

Check the two closures of the video link for bowed pins. In the event that they are twisted, fix them with a needle-nose pincers. This applies to VGA and DVI links.

Verify that the video link is connected immovably to the back of the screen and that the stuck end is firmly screwed into the video yield on the back of the PC’s case.

In the event that that doesn’t work, take a stab at evacuating the current link and supplanting it with a known working one.

Obtain a working screen from another PC and attach it. On the off chance that the screen doesn’t work, your video card may not work, and you will most likely need an expert to analyze the issue all the more intently.

The Computer Won’t Boot from the Hard Drive

Ensure there are no DVDs or blaze drives embedded in the PC.

Evacuate every single outer drive or gadgets and have a go at restarting the PC.

In the event that you get a progression of beeps or mistake messages, record them, as they could be instrumental in diagnosing your concern. Beep codes differ by producer, so counsel your BIOS (essential information/yield framework) documentation on the off chance that you have it for additional inside and out data on what those beeps mean. You can likewise get that data from the maker bolster page for that model.

On the off chance that you get a particular blunder message, duplicate the mistake message into a web crawler. You might have the capacity to analyze the issue that way. Try not to purchase or download programming promoted for it, however.

For more established PCs without a strong state hard drive (SSD), tune in to ensure your hard drive is turning. In the event that you hear a clicking sound, your hard drive never again works, and you should supplant it.

Numerous more up to date PCs have SSDs, which don’t turn. On those machines, hope to check whether the hard drive light is blazing. On the off chance that the hard drive light is blazing, yet the PC doesn’t start up, control the gadget off and afterward restart. In the event that the hard drive light doesn’t streak, that is a pointer that it has fizzled.

In the event that nothing unless there are other options works, verify whether the PC is under guarantee. On the off chance that it is, call the maker for technical support.

In the event that none of those choices apply, you will probably need to get some sort of expert help.

How to fix black screen problem on Windows 10
When your PC is experiencing a black screen, use this guide to troubleshoot and fix this issue on Windows 10.
Mauro Huculak
20 Jan 2017

Windows 10 has already proven to be a reliable operating system, but like with any piece of software unexpected things always will happen. Perhaps one of the worse issues you can come across is a black screen on your Windows 10 computer, because you don’t get an error code or message giving you an idea where to start troubleshooting.

An unexpected black screen can occur in a number of scenarios on Windows 10, stemming from issues with the graphics driver, a connection problem between with your display, during the installation of the operating system, updates… or it just can happen randomly at any time.

In this Windows 10 guide, we’ll walk you through a series of steps to help you troubleshoot and fix the black screen problem on your device.
How to fix black screen on your PC
Installation in progress

If you see a black screen during the installation process, depending on your hardware and data on your device the operating system may still working in the background. Sometimes it could take several hours to complete the process.

The best thing you can do in this situation is to wait, but if it’s been anywhere between 3 to 6 hours, then chances are that the installation process is stuck.

If the installation is stuck, you should try shutting down your device completely. You can force your computer to shutdown by holding down the power button for about 10 seconds or until it shuts down, and then unplug the power cord.

In the case that you’re using a laptop, it’s also a good idea to remove the battery if possible (though increasingly that is not possible).

Then make sure to disconnect all the non-essential peripherals, including external storage, phone, printer, game controller, network cable, and secondary monitor. If possible, also turn off your Wi-Fi and Bluetooth adapters. Only leave connected to your computer the essentials: keyboard, mouse, and display.

Wait 60 seconds, reconnect the battery and power cable, but do not reconnect any of the peripherals, and power on your computer.

If this was a mere hiccup, the installation process should resume and complete successfully. Once you’re on the Windows 10 desktop, remember to reconnect your peripherals and other devices.

If the installation process fails and rolls back, then keep your peripherals disconnected, and try to manually install Windows 10 updates one more time. In the case that you were trying to upgrade to Windows 10, you can try to upgrade one more time, but this time you can try using a bootable USB flash drive to install the operating system.
Double-check your video connections

If your computer gets a black screen before you sign into Windows 10, it could be a connection problem between your PC and the display.

In the case that you’re using a desktop computer, double-check your display is connected properly to a power outlet and your computer.

When possible it’s also a good idea trying to switch to a different video output. A lot of times a video driver can change and without a particular reason it can send the video signal to a different output port (e.g. DVI, HDMI, DisplayPort, Thunderbolt, VGA) or adapter.

If you installed a discrete graphics card, but your computer also includes an integrated video processor, you can also try switching the video connection to the integrated graphics as it could be a problem with the discrete card.

You can also try to connect a different monitor to your desktop PC or laptop to confirm that it’s not a problem with your primary display.

If the computer isn’t detecting the display, then you can try using the Windows key + P keyboard shortcut, press P again and then Enter. You’ll need to repeat this steps a number of times to cycle through all screen options.

If you’re connecting your PC to your TV, double-check the TV is turned on, and make sure to set the correct input to connect to your device.
Try to wake up the display

Many times it could happen that Windows 10 is just not detecting the display. Using your keyboard, you can use the Windows key + Ctrl + Shift + B keyboard shortcut to wake up your display.

In the case that you’re using a tablet, the process to wake up the display is a bit different, press the volume up and volume down buttons simultaneously three times.
Disconnect non-essential devices

An external device connected to your computer could be the problem of a black screen. Try disconnecting all your peripherals.

If everything returns to normal and you no longer see a black screen, then try reconnecting one peripheral at a time. If your computer monitor goes black again, then you may have identified the device that is causing the problem. Disconnect the device in question, restart your computer, and if the device continues to produce a black screen, contact your device manufacturer for assistance.
Boot in Safe Mode to troubleshoot and fix a black screen problem

In the case that there isn’t a problem with your external devices, there could be a number of other reasons, and you can boot your computer in Safe Mode to try to fix the problem.

You can get your computer to boot in Safe Mode in a number of ways, but in this case, you can do the following:

Start your PC.

At the sign-in screen, hold the Shift key down, click the Power button on the bottom-right, and select Restart.

If you cannot see anything on the screen because of a black screen, then start your PC, as the blue Windows logo appears, press the power button and reboot again. Repeat these steps three times until you trigger Windows 10 automatic repair. Follow the on-screen directions and launch the advanced options menu.

Once you’re the advanced startup menu, click Troubleshoot.

Click Advanced options.

Click Startup Settings.

Click the Restart button.

On the Startup settings, press 5 or F5 to enter in Safe Mode with Networking.

Once your computer is in Safe Mode, you can try the following troubleshooting steps:
How to reinstall your video driver

Another issue that can cause your computer to experience a black screen is a buggy graphics driver update, which you might have received through the Windows 10 update. Other times there isn’t a problem with the update, but the video driver may have got corrupted causing to malfunction and display a black screen.

If the video driver isn’t working correctly, you can uninstall it in Safe Mode, and then let the operating system reinstall the driver automatically upon restart.

Use the Windows key + X to open the power user menu and select Device Manager.
Expand Display Adapters.

Right-click the adapter and select Uninstall.

Quick Tip: You can also select Delete the driver software for this device option to remove the driver from your computer. Sometimes, this is recommended, but if the operating system can’t find the driver online, you’ll need to download the correct driver for your video adapter from your PC manufacturer’s website.

Click OK to confirm.

Restart your computer to complete the task.

Once your computer restarts, Windows 10 should automatically reinstall the video adapter driver and hopefully, the black screen will disappear.

If you’re getting a black screen on a device that you upgraded from a previous version of Windows, you may need to download updated video driver from your PC manufacturer’s support website to fix the problem.
How to disable fast startup

Sometimes the black screen problem keeps happening because fast startup is enabled on your computer.

While in Safe Mode, you can use the following steps to disable fast startup:

Open Control Panel.
Click on System and Security.
Click on Power options.

Select the Choose what the power button does link on the left pane.

Click the Change settings that are currently unavailable link.

Clear the Turn on fast startup (recommended) option.

Click Save changes.
Restart your computer to complete the task.

It’s important to note that depending on your hardware configuration, your computer may not include support for fast startup.
How to disable high contrast

If you have high contrast enabled on your computer, it could also be the reason why you’re getting a black screen.

While in Safe Mode, you can turn off high contrast using the following steps:

Open Settings.
Click on Ease of Access.
Click High contrast.

Select None from the drop-down menu to turn it off.

Restart your computer to complete the task.

Terminate Run Once processes

Run Once process can also the be the reason of black screen after signing into Windows 10.

To terminate Run Once processes on Windows 10, do the following:

Use the Ctrl + Shift + Esc keyboard shortcut to open Task Manager.
Check the Processes tab and Services tab and look for any instances of RunOnce.exe and RunOnce32.exe.
If you find an instance in the Processes tab, select the item, and click on End task. If you find an instance in the Services tab, right-click the item, and click Stop.
Click on File.
Select Run new task.

Type the following command to restart your computer:

shutdown -t00 -r

Click OK to execute the restart command.

Restart your computer to complete the task.

Create a new user account

A problem with your user account can also be the reason your computer is experiencing a black screen.

You can see if your user account is causing the black screen by creating a new account while you’re in Safe Mode.

To create a new user account in Safe Mode, do the following:

Open Start.
Search for Command Prompt.
Right-click the result and select Run as an Administrator.

Type the following command to create a new account and press Enter:

net user tempuser /add

Remember to change “tempuser” in the command for the name of the account you want.

Type the following command to change the account type to Administrator and press Enter:

net localgroup administrators admin /add

Don’t forget to change “admin” in the command for the name of your account.

Restart your computer to complete the task.

Note that you’re using Command Prompt instead of the Settings app to create an account. This is because, for some reason, Windows 10 won’t let you create a new user account using Settings while in Safe Mode.

Once you restart your computer, sign in with the newly created account. If your computer is no longer experiencing a black screen, then the problem was something on your old user account.

If this is the case, you may want to switch to the newly created account — for more help, you can use our guide to move your files, link your user profile with a Microsoft account, and to delete the old account.

Facebook lists user phone numbers for all to see
Published October 10, 2012

Is Facebook broadcasting your phone number?

Is Facebook broadcasting your phone number? (AP PHOTO/THE CANADIAN PRESS, SEAN KILPATRICK)

There’s no easy way to look up someone’s mobile-phone number. White pages? Nope. Directory assistance? Uh-uh.

It’s something that drives telemarketers and pollsters crazy, as there are millions of people, especially young ones, who don’t have any landlines and can’t easily be reached by strangers.

But it turns out Facebook has been openly listing mobile numbers all along, as Indian security researcher Suriya Prakash discovered recently.

Needless to say, he wasn’t happy about it.

“I would consider my most ‘personal’ data saved on Facebook to be my mobile number as it is somewhat of a bridge interlinking both my personal and online life,” Prakash explained in a blog posting this past Thursday. “I would not like people I don’t want getting a hold of it.”

Prakash had earlier told Facebook about his discovery, but the company told him there were no security issues involved as the rate of queries from a particular source would be limited as a guard against automated attacks.

Prakash found that that was true for the desktop version of Facebook, but not the mobile one.

[11 Facebook Privacy Steps to Take Now]

Try it yourself

To use Prakash’s method, log into Facebook on a desktop browser, copy this URL and paste it into the address bar:http://m.facebook.com/search/?query=123456789

Then substitute a Facebook friend’s mobile number for the number string and hit “Enter.” (Be sure to include the country code prefix — “1” for the U.S. and Canada, “44” for Britain, “33” France and so on.)

If your Facebook friend has listed his mobile number on Facebook, or if he’s got a Facebook app on his smartphone, it’ll show right up. In many cases, it works for “friends of friends” and for total strangers.

Why? As Prakash found, the default Facebook privacy setting for “Who can look you up using the email address or phone number you provided?” is “Everyone.”

(To see it yourself, click on the downward facing arrow next to the “Home” button in the upper-right corner of your Facebook page, then click “Edit Settings” next to “How You Connect.”)

Contacted by TechNewsDaily, a Facebook representative said this was a feature, not a flaw.

“The ability to search for a person by phone number is intentional behavior and not a bug in Facebook,” the representative wrote in an email.

“By default, your privacy settings allow everyone to find you with search and friend finder using the contact info you have provided, such as your email address and phone number. You can modify these settings at any time from the Privacy Settings page.

“Facebook has developed an extensive system for preventing the malicious usage of our search functionality and the scenario described by the researcher was indeed rate-limited and eventually blocked. We are constantly updating these systems to improve their effectiveness and address new kinds of attacks.”

Gold mine of information

Until yesterday (Oct. 8), a savvy telemarketer could have created a computer script generating possible mobile-phone numbers, then harvested whatever real names were matched to them through Facebook.

To prove it, Prakash did exactly that, running through thousands of possible mobile numbers in India and in New York City. (Unlike the rest of North America, New York an area code dedicated to mobile numbers.)

You can see a small subset — 850 names — of Prakash’s results here. If you’ve got a New York mobile number in the format (917) 5×2-xxxx, you may even be on it.

Another researcher, Tyler Borland, wrote an even faster script that looked up 10 numbers at once.

“I was able to verify data for 1 phone number every second,” Borland told Computerworld.

With a botnet of 100,000 hijacked computers, Prakash estimated, the entire Facebook mobile-phone-listing database could have been harvested in a few days.

Facebook tweaked its settings to limit the number of responses it would give to a specific IP address. But the method still works manually.

TechNewsDaily was able to find the mobile numbers of four strangers, all of whom had presumably not tweaked their default privacy settings, by slowly running through a list of 20 possible New York numbers.

Stumbling into it

Prakash discovered this Facebook feature after he noticed that his smartphone Facebook app suggested adding friends from his phone’s contact list, based on his contacts’ mobile-phone numbers.

In fact, he could see his contacts’ profile photos and link to their Facebook profiles, even without having “friended” them on Facebook.

“What it does is that it compares the contact list from your phone to the FB database to see if you have any friends that are in your contacts but not on your Facebook account,” he wrote. “I also later figured out that simply ‘searching’ a person’s phone number (including country code) will show you their account.”
