If, while using your computer, you encounter the ACPI.sys Blue Screen error, read on as this post will guide you in fixing the problem. The ACPI.sys file is a Windows operating system file that is related to the MSDN 2939. ACPI.sys, the Windows ACPI driver, is an inbox component of the Windows operating system. It is the one that supports the power management as well as the Plug and Play or PnP device enumeration. And so if this file ends up getting corrupted, it is known to cause a Blue Screen error. Another possible cause for the ACPI.sys Blue Screen error includes RAM issues, incompatible firmware, hard disk issues, corrupted drivers or malware infection, and so on. Here are some Blue Screen errors that can be triggered by the ACPI.sys file:

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

To fix the Blue Screen error associated with the ACPI.sys file, refer to the instructions provided below.

Option 1 – Try to recreate the ACPI.sys file

If the first option didn’t work, the next thing you can do is to recreate the ACPI.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named ACPI.sys and rename it to ACPI.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the ACPI.sys Blue Screen error is now fixed.

Option 2 – Try to update or rollback the ACPI Driver

The first thing you can try to fix the Storport.sys Blue Screen error is to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Tap the Win + X keys to open the Win X menu and from there, select the Device Manager.
• After opening the Device Manager, look for the ACPI.sys driver and right-click on it, and then select Properties.
• Next, go to the Driver section. Note that the rollback option would only be available if you’ve recently updated the ACPI.sys driver. So if you can’t see it then click on the Update Driver button.
• After that, Windows will automatically check for the problems that could be related to the Blue Screen error.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver. On the other hand, if updating the ACPI driver, didn’t work, you can also try to copy the ACPI.sys system driver file from the System32 folder of another computer that’s functioning properly and runs the same Windows OS version. Afterward, place it on your problematic computer and check if it fixes the BSOD error or not.

Option 3 – Run System File Checker or SFC scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

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.

 Reboot your PC.

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 like ACPI.sys. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.

Well if anyone told me just a few years ago that I will see the day when Microsoft releases a new OS based on Linux I would be very amused, but that day has come. Mariner is the newest OS out of nowhere. Microsoft’s new Linux Distro, dubbed Common Base Linux (CBL)-Mariner, isn’t the type of distro you’d want to install directly on any old machine. It’s primarily meant for cloud infrastructure and edge products. Specifically Microsoft’s Cloud and Edge products. But if you are curious, it’s possible to run. Juan Manuel Rey, a Microsoft Senior Program Manager for Azure VMware, recently published a guide to ISO CBL-Mariner image. With that, you can easily get it up and running. And you can build CBL-Mariner on an Ubuntu 18.04 desktop. So you can try it out since it is free. You can get it from here: https://github.com/microsoft/CBL-Mariner It is obvious that Microsoft aims to set itself as a leader in enterprise server environments with this move and it is very likely that it may succeed or at least give a good shake to its competitors, mainly red hat and Suse which are two dominant distros in that field. Many believe that they can win over by providing regular updates and package delivery via their already established system and that feature could be a turning point for some. In any case, time will tell and we shall see.

Google Chrome, Microsoft Edge, Mozilla Firefox are some of the leading browsers commonly used these days and they all include an embedded copy of the Adobe Flash Player. So if you are running a Windows 10 PC then you can have up to 4 copies of Adobe Flash Player; one for Microsoft Edge, one for Internet Explorer, one for Opera, one for Firefox. You might also experience cases wherein two flash players are simultaneously running, i.e. one installed in Chrome as a single plug-in and another one installed in Windows, trying to parse the data. And in such cases, you might consider removing or uninstalling one of the versions of Adobe Flash Player. If you do, then you’ve come to the right place as this post will guide you in disabling the embedded Adobe Flash Player in Windows 10. Before you get started in removing the Adobe Flash Player in Internet Explorer & Microsoft Edge browser, you need to sign in with your administrative account even if don’t use it or set it as the default browser. After you’ve signed in to your administrative account, follow the steps below. Step 1: Open your browser, if you are using Edge then open it. Step 2: After opening your browser, go to its Settings and select Advanced Settings. Step 3: Next, Move the slider against the “Use Adobe Flash Player” option to off. Step 4: After that, open File Explorer and navigate to this address, “C:/Windows/servicingPackages” and from there, check on the following entries:

• Adobe-Flash-For-Windows-Package~31bf3856ad364e35~amd64….(version number of the Flash Player)
• Adobe-Flash-For-Windows-WOW64-Package~31bf3856ad364e35~amd64….(version number of the Flash player #)
• Adobe-Flash-For-Windows-onecoreuap-Package~31bf3856ad364e35~amd64…(version number of the Flash Player)

Step 5: Take note of all the listed package names of Adobe Flash Player and tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor. Step 6: Next, right-click on the three keys which have the name of the packages you listed and select “Permissions” one after the other. Step 7: Then check “Allow” to enable full control for the Administrators account and click OK to save the changes made. Step 8: Select the three keys one after the other and select Visibility DWORD located on the right side and then right-click on Visibility and change the Value data from 2 to 1. Step 9: Go over the same procedures again for the other keys. Once you’ve completed then you should now be able to remove packages using the DISM tool. Step 10: Simply open an elevated Command Prompt and execute the following commands:

• dism /online /remove-package /packagename:Adobe-Flash-For-Windows-Package~31bf3856ad364e35~amd64-10.0.17134.1
• dism /online /remove-package /packagename:Adobe-Flash-For-Windows-WOW64-Package~31bf3856ad364e35~amd64-10.0.17134.1
• dism /online /remove-package /packagename:Adobe-Flash-For-Windows-onecoreuap-Package~31bf3856ad364e35~amd64-10.0.17134.1

Keep in mind that the numbers at the end could be different on your computer due to the difference of version number so you have to use the numbers on your system. After that, reboot your computer.

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.
