Hey guys!
For a few months now my pc has on and off been doing this thing where it black screens when im gaming. My screens both go black (one is 165hz ips and other is a 360hz oled, idk if that matters but I think it MIGHT HAVE started happening after my oled arrived, cant recall 100%), both of them say "No Signal" and I can hear audio for maybe 10ish seconds. Sometimes along with that my fans go louder and I cant do anything but press the force restart button. When I restart its fully normal.
It only happens after maybe 40 minutes of playing, so for example I can play almost 2 Overwatch comp games or a single CS2 comp game. Today it happened for the first time in a few weeks. Every time it starts doing it I undervolt it a bit, then it doesnt do it anymore for another 1-5 weeks.
Temps for both GPU and CPU seem fine, both are around 70-80 celsius max. My BIOS is up to date, DDU did not help when I removed everything and updated drivers. The graphics driver reset shortcut doesnt do anything except a little beep and nothing changes.
I'm very lost because I have no idea what to do now. I know it could be a hardware related issue but my budget is not big enough to buy a new gpu, is there any other way I could find out if they're broken? My friends don't really have computers so I can't really borrow their parts. It's hard to replicate this except maybe just letting a game run for an hour and seeing if it happens or not.
(I built my pc in 2021)
GPU: TUF 3080 OC

CPU cooler: Noctua NH-D15
RAM: G.Skill 32GB (4 x 8GB) Trident Z RGB, DDR4 3600MHz, CL16

I'll do anything to get this fixed I'm so tired!!
