Answer 1

Hi there,

BSOD can really be painful to users and my first suggestion would be to update all the drivers and the BIOS of your PC.

You can also troubleshoot all kinds of BSOD from here
https://support.microsoft.com/en-us/sbs/windows/troubleshoot-blue-screen-errors-5c62726c-6489-52da-a372-3f73142c14ad

Corrupted system files are one of the possible reasons why this issue is happening. Try the below steps and see if they are helpful

Press F8 while booting your computer to access System Recovery options.
Click Troubleshoot.
Select Command Prompt.
Enter the following commands below, then press Enter after each command:
chkdsk c: /f
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
bcdboot c:\windows /s c:

Once done with the above commands, restart your computer and see if the problem is fixed.
