How to Fix win32kfull.sys BSOD SYSTEM_SERVICE_EXCEPTION on my Windows PC?

Andrew Strauss 26 Reputation points

I have been constantly getting the SYSTEM_SERVICE_EXCEPTION bsod with a mix of win32kfull.sys and win32kbase.sys. I seem to only get them while playing league of legends. I have run memtest86 with no errors and updated my video drivers.

Already tried some solutions provided on the internet and nothing helps me to solve this issue. Suggestions needed!

I'm not able to find a proper tag to add this question. Kindly ignore if the tag is wrong.
