A little more than a month ago I upgraded my gpu from a STRIX 1080 to a STRIX 2080TI OC, never had any issues... until a couple of days ago.
I have a 2700X, Gigabyte X470 Aorus Gaming 7 WiFi and a EVGA SuperNOVA 650 P2.
This is what happened so far:
- Yesterday my computer began freezing/powering off apparently at random after starting it and launching a game (DMC5) after a couple of minutes. After rebooting all went perfectly fine and I was able to game for a couple of hours without issues.
- Yesterday afternoon when I turned the PC on again, the same situation happened. After a few minutes, freeze (forcing a reboot). Then after reboot all ok.
- This morning, again same situation.
- this afternoon tho: every time I start an intensive game (PUBG, DMC, Tomb Raider) the issues appears after a few minutes. Sometime when it freezes, screen goes black and then the motherboard does 3 short beeps before powering off by itself, then it reboots.
However now even after rebooting I can't play any game. Browsing, youtubing etc works fine but as soon as I do something heavy graphic related, the issue appears. I tried Cinebench which is heavy on the CPU and nothing happened. As soon as I tried 3 mark, tho, again freeze.
I've found this thread here saying it could be PSU related, but my question is: why then for a whole month I never had issues and now suddenly 650W are no more enough? I'm already using two separate cables because I knew that it's advisable with such power hungry cards but still.
I didn't do any hardware changes or major things... no OC, both CPU and GPU are stock clocks.
