so i got a pc a few days ago and when i benchmarked it it was fine then when i tried to play the finals it does this weird lines then the gpu restarts so i went to the guy i bought the pc from so he changed some power cable and he benchmarked it then i went to another guy who ran heaven benchmark for about 20 mins and it seemed fine then i went home and its still happen for contex its an xfx rx570 8gb what i suspect that the heat is doing this it reaches around 88-90 and i tried to change the thermal peast on the gpu but it really didnt help i wanna know if the gpu is fried
 
Given the age of the components, it could be a number of things, including the PSU failing to provide adequate power when under a heavy load.
how can i be sure tho i have a three month waranty but when i went to the guy everything was fine and it plays good for bit then crashes with me atleast idk if its the psu
 
Understood. How old is it?

Does removing it from the equation resolve the issues previously noted?
come to think of it this didnt happen if i just whatch you tube or like non gaming but when i open a bunch of app and a game it happen so maybe its consming toomuch power that the power strip isnt handling
