Hello, I have an issue with my PC. Couple days ago FPS drops started to happen and every game is unplayable. This is my system :
Motherboard : ASRock 970 R2.0 (BIOS ver : P2.80)
CPU : AMD FX-8300, 3.3GHz
CPU Cooler : Arctic Xtreme Rev. 2
GPU : Gigabyte Radeon R9 280x 3GB Windforce
Memory : Kingston HyperX Fury Black 8GB (2×4GB) DDR3-1600
PSU : Seasonic S12II 620W 80+ Bronze

I've tried updating BIOS (P1.8 > P2.8), disabling "Cool 'n' Quiet" in BIOS, disabling "Game DVR" via regedit, updating all drivers, puting resolution to minimum, cleaning dust from pc case, added one more case fan pointed to cpu to cool it more down. None of that helped, I still get constant FPS drops in every game i open. I don't know what could be the reason so I would like to hear from you :D Thank you very much !!
