My computer display turns off randomly when playing games. The monitor will blank out then go to the no input screen. I need to then do a hard reset to get it to display anything again. My computer is not overheating so what could this be. I ordered a power supply tester. But what would you think would cause this. I am leaning towards my GPU.
Was having the exact same issue a few days ago. Had a ASUS 660 ti and swapped it out for my gigabyte 7770 and everything has been running fine since. Just need to figure out if it's either the card or the PSU.
