I've had my FX-8150 for almost 4 years now and it's been running great, causing no problems at all. It's been running overclocked from 3.6 to 4 GHz for the past 3 years.
Two days ago, I restarted my PC and suddenly I had extreme stutter in games like CS:GO and Overwatch.
First I thought it was my GPU but after reinstalling it's software (I have a GTX 960) and some testing, I found out that the stutter only happened when I moved the mouse (2 months old mouse, a ROG Gladius).
I reinstalled the mouse software (ROG Armoury) and created a new profile in it but this didn't help either. Lowering the polling rate in the mouse software seems to help but I have to put it all the way down to 250 or lower for games to playable (I've been running with 1000 polling rate since I got this mouse without any problems).
When moving the mouse around on my desktop, I can see that the CPU usage increases with 10-20% so something is wrong..
Today I removed my CPU overclock (reset to stock speed) and when running a game with no other programs running, it works great but as soon as I start up a program like Mumble or Chrome, the stutter returns and it seems that the more programs I run, the worse it gets.

What I'd like to know is, is the CPU dying? If yes, which other AM3 CPU should I invest in? If no, what can I do to fix this stuttering problem?

I need to be able to run extra programs while I play, just like I could a few days ago..
 
Solution


I decided to uninstall everything under Human Interface Devices while only my mouse was plugged in and this seems to have solved the problem. At least, now I don't have any stuttering while playing Overwatch with 1000 polling rate.
As it's getting late here, I'll stop now and do some more testing tomorrow, and hopefully the problem is solved..
If it really is solved, it must have been a corrupt USB driver or smt like that. Not sure how that could happen.

Thanks for...

I've noticed that Windows 10 has some issues with making things extremely slow from time to time. It eventually got to the point where the system could no longer run games because its too slow doing something. I fixed it by doing:
Opened a cmd prompt as admin and ran these lines:
SFC /scannow
DISM /online /cleanup-image /scanhealth
DISM /online /cleanup-image /restorehealth
Then restarted.

Yup simple error scan cleaned the system right up.
