1] Roll Back the GPU driver

Roll back your GPU driver (if it has been updated recently). Sometimes, the latest update causes problems due to bugs. This might be the case with you.

Follow these steps:

Open the Device Manager.
Expand the Display adapters branch.
Right-click on the GPU driver and select Properties.
Select the Driver tab.
Click on the Roll Back Driver button (if clickable).

2] Perform the Clean Installation of the GPU driver

If rolling back the graphics card driver does not help, performing the clean installation of the graphics card driver can help. Before proceeding, download the latest version of your graphics card driver from the official website of your computer manufacturer.

Now, download and install the Display Driver Uninstaller (DDU). Start your system in Safe Mode and run the DDU utility to completely remove the graphics card driver from your system. Now, run the installer file to install the GPU driver from scratch.

3] Test your RAM

A faulty RAM can also cause a BSOD error on a Windows computer. To confirm this, test your RAM with the help of the Windows Memory Diagnostic tool. If your RAM is faulty, consider replacing it.

4] Repair your system image files

One possible cause of this problem is the corrupted system image files. Scan your system for system file corruption with the help of System File Checker and DISM tools. These tools will automatically fix the corrupted system image files (if exist).

5] Reset your PC or perform a System Restore

If nothing helps, the last resort is to reset your PC to the factory default settings or perform a System Restore. The System Restore tool takes back your system to the previous point in time. First, restore your system by selecting the restore point that was created on the date after which the issue started occurring.

If System Restore does not help, reset your PC to the factory default settings. Select the Keep My Files option while resetting your PC because this will not delete your data. However, taking a backup of important files is always a wise decision before proceeding.

That’s it. I hope this helps.
