Issue: How to fix SYSTEM_SERVICE_EXCEPTION (win32k.sys) error?

Hello. I have had Windows 10 for, and everything worked smoothly. However, a few days ago, I started encountering a blue screen, and it repeats at random times, without any pattern. I get the following error message: SYSTEM_SERVICE_EXCEPTION and then it mentions wink32k.sys.
