Random BSOD

Hello there,

I've been getting these random BSOD's and I have no idea what is causing them. I can't remember updating or installing anything that could have caused them to start.

However, when BSOD appears on my screen, I was reading those lines and it pointed out something about this file:

Code:

win32k.sys

When I restarted PC, message appears:

Code:
