So I have been having a problem of FPS dropping in games after playing for awhile. Reboots seem to help but it has a diminishing return. After I reboot i'll have good FPS anywhere from 10 minutes to an hour and a half.
My drops happen randomly and do not coincide with heat problems. I have had some light artifacting at times (small black squares) but it seems to fix itself with a game reboot and is only within the games and not anywhere else. I have recently changed my CPU and Motherboard in the last week and was having the same problems beforehand with the old board and CPU.
My graphics card is not overheating as the highest I have seen is about 80C and that is about normal for my card (AMD Radeon HD 7700).
All my graphic drivers are up to date. My computer is clean. All my fans are running (yet my case fan and gpu fan seem to be quite loud at times even outside of games). My PSU is fairly new as well (under two months) and is well within the range for my power usage needs.
I am drawing a complete blank and have no clue what is exactly going on.
