So if you have someone to buy a gift or just want to drop a few great games in your library at a low price this is the time when you should do it.

Installing Windows updates, installing a new driver from the manufacturer, or even just installing an application or game can cause sometimes certain components of your computer to stop working properly or introduce issues that were not present just before mentioned installation. Luckily for all of us, Microsoft seems aware of this potential issue and we have the option to roll back an older driver which performed well and had no issues at all. In order to do this first press ⊞ WINDOWS + X to open the hidden start menu and click on Device Manager. From the Device Manager choose the troublesome device and right-click on it, choose properties. Device properties floating Window will appear. Click on the top tab which says, Driver. From the Driver tab, click on Roll Back Driver. Note that if the device is working properly, the Roll Back Driver button will be greyed out and you will not be able to click on it meaning that chosen device is not the issue. If the device is not working properly and you can click on Roll Back driver, do it, choose the previous version, and reboot your computer. You can use this method to get back to the previous driver version for any device that is causing issues in your computer.

In case you don’t know, there is a built-in tool in Windows 10, known as Reliability Monitor that provides a day-to-day snapshot of the health of your system. It warns users of any looming issues or disasters before your computer breaks down finally. So obviously, Reliability Monitor is useful, however, there are times when it could behave incorrectly. For instance, it might fail to show you any updates even when they are installed. Thus, if you experience any malfunctions with the Reliability Monitor tool in Windows 10, read on as this post will guide you in updating or working in Windows 10. To fix the problem with the Reliability Monitor, there are several fixes you can check out. You can try to enable the data collection for Reliability Monitor or reset it, as well as put your computer in a Clean Boot State. For more information, refer to each one of the options given below.

Option 1 – Try to enable the Data Collection for Reliability Monitor

The Reliability Monitor tool uses data provided by the RAC Agent scheduled task and it will start to display a Stability Index rating and specific event information 24 hours after the system installation. The RACAgent scheduled task, by default, runs after the operating system is installed. And if it is disabled, it must be manually enabled from the Task Scheduler snap-in for MMC or Microsoft Management Console. Thus, you need to enable the Data Collection for Reliability Monitor to fix the problem.

Option 2 – Try to reset the Reliability Monitor

The next thing you can do to fix the issue with the Reliability Monitor might want to reset it to resolve the problem. If the Reliability Monitor is already open, you have to close it and open it again. After the reset is done, it may take up to 24 hours for the Reliability Monitor to display results again. This should fix the problem.

Option 3 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Black border issue. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

When it comes to booting an operating system on a computer, one of the most essential pieces of software you can use is the UEFI. In fact, a lot of users now prefer to use UEFI instead of BIOS. It also depends on whether the UEFI or the BIOS is supported on the motherboard. Recently, a number of users reported an issue with UEFI where they were unable to find it under the Advanced Options screen where it’s supposed to be located. The missing UEFI Firmware settings in the Advanced Options could be caused by several reasons. It is possible that the access to the UEFI menu is blocked or it could also be due to the Extra Fast Startup feature being enabled. It is also possible that the operating system is installed in Legacy mode. There are several options to try to fix this issue. You need to check if your computer supports UEFI or you could also try to disable Fast Startup or bypass the Extra Fast Startup feature. You can also use a boot to UEFI shortcut as well as check the CMOS battery.

Option 1 – Try checking if your computer supports UEFI

The first thing you have to do is to verify if your computer supports UEFI. If your computer does not support UEFI, then it’s no wonder why you don’t see the UEFI Firmware settings in the Advanced Options.

Option 2 – Try turning off Fast Startup

• First, boot your computer in Safe Mode.
• Once your computer is booted in Safe Mode, tap the Win + R keys to open the Run dialog box and type in “control” to open the Control Panel.
• Next, click on the Hardware and Sound section and click on Power Options.
• Afterward, select the “Choose what the power buttons do” option from the left side menu pane.
• Now click on Change settings that are currently unavailable and uncheck the entry that says, “Turn on fast startup (Recommended)”.
• Then click on Save Changes and restart your computer and see if it has fixed the problem or not.

Option 3 – Try bypassing the Extra Fast Startup feature

As mentioned, the missing UEFI Firmware settings could be due to the Extra Fast Startup feature. To fix it, you have to disable this feature. All you have to do is tap and hold the Shift key and click on the Shutdown button from the Start button. This will boot your PC with the UEFI booting from the beginning and then use the hotkey for your motherboard to boot into the UEFI setup.

Option 4 – Try using a boot to UEFI shortcut

• Right-click on any empty space on your Desktop and select New > Shortcut.
• This will open a new mini window. And here, you have to type this in the text field: shutdown /r /fw
• After that, click on Next and name the desktop shortcut and then click on Finish.
• Next, right-click on the newly created shortcut and select Properties.
• Click on the Advanced button and select the “Run as administrator” option.
• Now click OK to save the changes made. Each time you execute this shortcut, your computer will automatically be booted to the UEFI Firmware Settings.

Option 5 – Try to check the CMOS battery

Another thing you can do is check the CMOS battery physically on the motherboard and see if it has to be replaced since a damaged CMOS battery can also cause the issue with the missing UEFI Firmware settings.

Option 6 – Set your computer from Legacy to UEFI

If applicable, you can try to set your computer from Legacy to UEFI to resolve the problem.

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: mbr2gpt.exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

Things have stirred lately with Chinas ban on crypto mining and many used GPUs will flow the market probably. But should you buy a used GPU? Short answer: NO, long answer: keep on reading to find out why.

GPU shortage and its cause

As you all know by now, we live sadly in a world struck by a global Pandemic. Due to this awful disease and measures taken against it, many people are either working from home or are at home making the manufacturing of new chips problematic while demand on the market has raised. Throw into that mix crypto mining which has raised in popularity and you have, well today's market where we have GPU shortage. Now with the latest news that China has banned the mining of cryptocurrency, there is to be expected that at some point in time mining cards used there will fit the market in the whole world. Sadly even with a large quantity of GPUs that will become available, the overall price of cards will not be much lowered I am afraid since demand is still very high and many people would not want to purchase used mining cards and neither should you.

Be prepared for the worst scenario

Although this sounds very pessimistic and in most cases, it will not turn out to be true, you should always prepare yourself mentally that you might be in that lower percentage that will end up with a really bad GPU. What has come up to be absolutely true when considering GPU that were mining is that if anything at all can be done to GPU in order to increase performance, it has been done. Miners want to optimize and almost every GPU if could be overclocked, it was overclocked. Extensive mining also means that thermal paste has been dried and it is pretty useless at this point and there is a very high chance that fans and heat sinks will need much cleaning or even replacement raising the price of the card itself for mentioned paste, fans, and heat sinks. There's no way to tell what the previous owner might have done with a graphics card when you're shopping online, so our advice is to assume the worst. Don't trust the seller to give truthful information. Any listing that says it was "never used for mining" at this point is probably a lie.

Age of the GPU matters

Date when GPU itself has manufactured really matters. Newer cards even if used extensively have been used for a much shorter period of time and are not so damaged were ones produced a few years ago have seen a lot of action. Let’s say that you get RTX 3060, In the worst-case scenario it has been mining since late February of 2021 and basically, it is still under warranty so it should behave OK and put some good work in gaming even in that state. On another hand, if we take for example GTX 1080Ti which is 4 years old GPU things start to change drastically. 4 years GPU could be worn out even if it was used just for extensive gaming sessions let alone for mining.

No return policy and seller rating

Most of the time you will run into a product that cannot be returned or no refunds policy. This should bring a red flag right away and deter you from purchase. Sellers with the highest ratings are more trustworthy since many of them will not want to destroy their reputation but these will probably not even have these kinds of merchandise in their store. Buying with a poor rating seller and no return policy on a product is just asking for trouble. And although some stores do have arbitration and will stand on the customer side there is no guarantee for that and it will take too much time to process.

If you really must buy a second-hand GPU

Of course in these troubled times sometimes due to malfunction or any other reason, there would not be another choice than to buy a second-hand GPU. In this case, if there is no other option consider sellers with many positive ratings. If you can buy locally that would even be better or the best-case scenario would be if you could visually see and inspect GPU itself in order to see in what state it is. Look for warranty stickers to see if they are thorn and the card has been tampered with. Also take a good look at screws, if they have scratches card has been opened, probably to replace fan or heating sinks which means that it has worked a lot.

Conclusion

It is very difficult to give the best possible advice on this situation since of GPU shortage, but I would much prefer a new GPU with lower performance than a hi-performance one which was mining.

One of the common causes of Blue Screen of Death or BSOD errors is system driver files due to varying reasons. So if you encounter a Stop error caused by some system driver files such as isapnp.sys, gv3.sys, storahci.sys, or myfault.sys, on your Windows 10 PC, then this post should help you fix the problem. These system driver files are associated with different error codes. The isapnp.sys file is related to the following error codes:

• SYSTEM SERVICE EXCEPTION
• PAGE FAULT IN A NONPAGED AREA
• KERNEL DATA INPAGE
• SYSTEM THREAD EXCEPTION NOT HANDLED
• IRQL NOT LESS EQUAL
• KMODE EXCEPTION NOT HANDLED.

While the gv3.sys file is related to the following BSOD error codes:

• IRQL NOT LESS EQUAL
• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN NONPAGED AREA.

On the other hand, the storahci.sys file is related to these error codes:

• IRQL NOT LESS EQUAL
• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN NONPAGED AREA.

And the myfault.sys file is associated with this error code: SYSTEM SERVICE EXCEPTION. Although this system driver file causes different kinds of Blue Screen errors, some of their potential fixes are quite the same so you need not carry out tons of troubleshooting steps. But before you troubleshoot the problem, you might want to check out System Restore first, especially if you create a System Restore point from time to time. To perform System Restore, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

If System Restore didn’t help in fixing the Blue Screen error, now’s the time for you to resort to the troubleshooting tips provided below but before you get started, make sure that you create a System Restore point first and boot your computer into Safe Mode.

Option 1 – Use the System Configuration utility

Note that this first fix is only applicable for Blue Screen errors associated with the myfault.sys file.

• In the Cortana Search box, type “MSConfig” and click on the “System Configuration” entry to open it.
• After opening System Configuration, go to the Processes tab.
• Then scroll down and look for the “Digital Line Detection” process and disable it.
• Now restart your computer and check if the Stop error is fixed or not.

Option 2 – Try to update, rollback or disable related device drivers

Incompatible and outdated drivers can also cause computer malfunctioning or crashing as well as Blue Screen errors. To fix that, you can update, roll back or disable the device drivers in your computer.

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• After opening the Device Manager, from the list of device drivers, look for the “WIN ISA Bus Driver” if you are facing a Stop error related to the isapnp.sys file. While you have to look for the Sony Recovery CDs PCG-Z1RAP Series device drivers if you face a Stop error concerning the gv3.sys file. For the storahci.sys, on the other hand, look for any outdated drivers and update them.
• To update or roll back or disable these drivers, just right-click on each one of them, and depending on your preference, you can either select “Update driver”, “Disable device” or “Uninstall device”.
• After that, restart your PC and see if it helped in fixing the Blue Screen error.

Option 3 – Use System File Checker

One of the built-in tools in Windows that you can use to fix Blue Screen errors is the System File Checker. This built-in command utility can help you restore corrupted or missing files as well as replace bad and corrupted system files. Chances are, any of the aforementioned system driver files might be corrupted so to fix them, use System File Checker.

• First, right-click on the Start button and click on the “Command Prompt (Admin) option.
• Next, type in the sfc /scannow command and hit Enter to execute it.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Now restart your computer.

Option 4 – Run the Blue Screen Troubleshooter

Troubleshooting Blue Screen of Death errors wouldn’t be complete without the Blue Screen troubleshooter. As you know, it is a built-in tool in Windows 10 that helps users in fixing BSOD errors. You can find it in Settings, under the Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options.
• Note that you might have to boot your PC into Safe Mode.

One of the smoother things that Microsoft did with the Windows 10 operating system is to separate Cortana from Search. This means that Cortana is strictly now a voice assistant and many users have seen it coming since not everyone uses Cortana. In addition, it also paved the way for other virtual assistants like Alexa to get on board with Windows 10. And now in the newly released Windows 10 v1903, Windows has brought the Voice Activation under Privacy. In this post, you will be guided on how to perform the Voice Activation troubleshooting on your Windows 10 computer. To use Voice Activation in Windows 10, follow, in the Start Search, type “voice activation” and click on “Voice activation privacy settings” listed in the search results. And from there, you can choose to allow apps to use Microphone, like listen in the background as well as select which app can access it. Each time enabled voice assistants continue to listen via microphone for the voice keyword, the app will activate itself for the keyword and will react depending on what you ask it. So if you are using a voice assistant and it didn’t respond when you speak the keyword, just go to Settings > Privacy > Voice Activation and follow these steps:

Option 1: Check the App permission to use the voice activation feature.

You have to make sure that the toggle button for the Voice activation feature is turned on globally. It can be found under the “Allow apps to use voice activation” section. You also have to ensure that the microphone is available for apps that use this feature.

Option 2: Voice activation is not working under the lock screen.

If you tend to use the voice assistant even when your computer is locked, Microsoft has a specific setting that you have to turn on. You need to make sure that the toggle button for the “Allow apps to use voice activation when this device is locked” option is turned on. However, keep in mind that the voice assistants are not locked to only recognize your voice as they also answer to anyone who will use the voice keyword.

Option 3: Check the individual permissions of apps.

If the voice assistant is not working, you have to check each one of the apps’ permissions for voice keyword, and the option to work under locked condition works.

Option 4: Run the Microphone troubleshooter.

If you’ve verified that the settings are in place, then you have to run the Microphone troubleshooter by simply going to Settings > Privacy > Microphone. From there, make sure that the toggle button for the following options is turned on:

• Allow apps to access your microphone
• Enable microphone access for the voice assistant

And if it’s a desktop app, you have to enable the toggle on at the end.
