2. Keep Windows 10 up to date

BSoD errors are often caused by hardware and software issues, and in order to fix these issues, you need to update Windows 10.

New patches are released frequently, and many of these patches fix both hardware and software issues. You can download the latest patches easily through Windows Update.

Microsoft is constantly working on Windows 10, therefore if you wish to keep your PC stable and error-free, we strongly advise that you download the latest patches.

3. Remove problematic applications

Third-party applications can often cause these types of errors, therefore it’s important that you find and remove any application that might be causing this error.

According to the users, applications such as ASUS AI Suite can cause these errors, so if you’re using this or any other similar application, be sure that you remove it.

Another common cause can be your antivirus software or firewall, therefore you’ll have to remove all third-party antivirus programs from your PC in order to fix this error.

Even if you remove your currently installed antivirus, your computer will still be protected by Windows Defender, so you don’t have to worry about online safety.

We have to mention that uninstalling the antivirus software might not fix the problem since many antivirus programs tend to leave certain files and registry entries behind once you uninstall them.

To completely remove all files associated with your antivirus program, we strongly advise using a dedicated removal tool. Many antivirus companies have these tools for their software.

According to users, McAfee antivirus was the cause for this error, but bear in mind that almost any antivirus program can cause this error to appear.

We have to mention that sometimes drivers can cause these types of errors, therefore you might have to uninstall a certain driver from your PC.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

Rather often Blue Screen of Death errors are caused by outdated or buggy drivers and the only solution is to update the problematic drivers.

 Updating drivers isn’t that hard, and you can do that simply by visiting your hardware manufacturer’s website and downloading the necessary drivers for your device.

Bear in mind that you might need to update drivers for all major components in order to fix this error. Searching for drivers on your own can be time-consuming.
