PC resets after 20~ minutes of playing games (except league of legends), it started happening after I replaced the PSU (og psu was some no name dont know what the voltage was) with a corsair CX850M and replaced the gpu (was a gt 720) with an rx 470). the gpu is also (at least in counterstrike) at 0% usage most of the time, sometimes going to %100 for a split second even though im geting well above 100fps, but for some reason in spectator mode a get lots of stuttering. Tried to fix it by doing a fresh install of windows 10 but that didnt work.
