What exactly were the max temperatures of the CPU and of the GPU you measured?
Check the fans, clean the inside. To be sure about the heat, run with the side cover off and a fan blowing into the for extra cooling.
Undo all overclocking.
See if the BIOS needs to be updated.
Anyway, this looks like a hardware issue. Things to replace, as an experiment, if the above doesn't help: fans and heat paste, PSU, graphic card, motherboard, RAM.
So for about 2 months my PC has been restarting while playing games ( sometimes 2 times with in an hour, and sometimes I can play the whole day with no problems) I read forums and watched so many videos. Everyone says that my PSU is what the problem is but I thats isn’t the problem. Also I don’t have any colors on my screen when this happens (Not Blue or black) I have watched my temps closely and that isn’t the problem eathier. My game will freeze and then the PC will restart. Only when playing games...
Does anyone have any ideas? What could be my problem?
