Hello i gave my brother my older pc it is an i5-6500 with a 1070 when i hand that pc i was able to play my normal playlist of games (Overwatch,PUBG,CSGO.Call of duty black ops 4 and more) At great fps's but now he is not able to even run a game on 1047x900 at 20 fps. The only thing i can recall that his pc once blue screened on him once for an overheating cpu and i changed his cooler with a new one CPU and GPU temps are not bad They never peked past 80 c but do you think that the CPU overheating that one tome caused all this
P.s sorry for my English if it was bad English is not my first language!
