So this issue began after i didn't use my pc for a month. While playing a game (cs go)there is a bottle neck where the cpu runs at 70-90% while gpu is only at 5-10% causing the fps to drop from 90fps to an eye bleeding 8fps (@800×600). The bottel neck didn't exist before. The cpu temp are around 45-47°C (113-116F). I've even changed the PSU and cleaned the hardware of dust but saw no difference. Even doing basic tasks like browsing web and watching YouTube videos has become a pain.
