GPU Drops to 4% causing low FPS

[emailfaker110]

I have read thousands of aticles now but could not find a solution:

While playing games like CSGO or PUBG my GPU/CPU usage drops from 50% to ~3%:

This causes fps drops from sometimes 300+ to ~40 wich is really annoying.

PC SPECS:

GeForce GTX 960
AMD FX(tm)-8350 Eigth Core
12 GB RAM
Windows 10

Any ideas on how to fix this?

And yes, my drivers are updated.

What's your cpu doing at the same time? Any cores maxing out?
What motherboard do you have?

My CPU does the same as my GPU, going up and down. Dir example: Im playing CSGO and it loweres the GHz from 4 to 1. The usage drops aswell. Ill have to Look Up my Motherboard tomorrow, where can I find it?
