Fps drops lower than usual

I think your fps drops are happening because your GPU keeps timing out (several errors of the same type).

Event Name: LiveKernelEvent
Response: Not available
Cab Id: 0

Problem signature:
P1: 141

I recommend removing all drivers with Display driver uninstaller, and then installing the latest driver for the card.

You may need to update your BiOS (it’s already outdated when you buy a new PC). See this thread from the staff for more info:

I also noticed you have some older Windows files (did you upgrade from 8.1?) that are reporting errors. I recommend closing background apps to address that.
