About 3 weeks ago I got my PC back from a repair shop and the CPU, Motherboard and Ram had been changed. For about a week after that everything was running fine with no issues. Suddenly all my games were running with way lower fps than normal. In csgo my fps are normally around 250-290 and CPU usage 80-100%. Now i get 40-60fps and CPU usage is 30-50%. In csgo alt tabing out of the game and back in makes it play normally but this doesn't help in any other games (Rocket league, Rust, H1Z1, mirror's edge catalyst). I can get my cpu usage to 100% with stress tests. My GPU usage and temps are as they used to be before this happened. When i got my PC back from the repair shop I updated the bios because it was only showing my SSD and not my HDD. I have downgraded my bios back but it didn't help.

 
I have the same exact problem! does it kinda look laggy when you move around in csgo? I had 350 fps now I get 50-200 with lag spikes and everything. If you know a fix let me know also if I get it fixed il let you know. Sorry I couldn't help but you're not alone!
 


Yeah it's very laggy. Does the alt tabing out and back in to csgo help you? And do you have the same problem with other games?
