So I built a new computer and at first it was operating fine, but after about a month I started experiencing problems like the computer locking up while playing games or watching youtube videos. Also major FPS drops in games. This would be an on and off thing for a while sometimes the computer would act normal and other times I wouldn't be able to get 15min on it. Since these problems have started to occur I have swapped out a lot of my parts to try and find the source. I have also replaced with new, Ram, Video Card, and PSU. I have reinstalled drivers for video cards, rolled them back, defraged disk, reinstall windows, run multiple malware programs, adjusted power options to performance. I have also replaced with new, Ram, Video Card(friends worked on his computer right before he gave it to me no way there's anything wrong with it), and PSU. I think I have gotten the computer to stop locking up, I am not sure how but it hasn't in a while after reinstalling windows but I have not fixed the fps problem and the weird activity when i want to browse the web. I am about to bring my computer to a fix shop unless I can get a an answer here.
