Hey guys, just looking for a little bit of advice on how to move forward here. I’ll list all specs at the end of the post and feel free to ask if you need any further info but I’m officially stumped lol. So I’ve noticed lately that my main monitor flashes dark maybe once every 10 or so minutes and in the top left shows the source as if I’ve changed it to hdmi from DP or something even when I haven’t. Screen goes dark for like 5 seconds and comes back to life like nothing happened. In a vacume I wouldn’t care that much but last night it got me killed so many times that it’s apparent it’s a bigger problem then I first thought. I’ve tried the usual things (win update, driver update, reseat GPU and all cables, swapped ports on monitor and GPU side) and while nothing else seemed to have an effect, trying to update my drivers puts both screens black and they do not wake up unless I suffocate the power button. I’m stumped truly. Makes me think it’s a driver issue but as of now I can’t even seem to reinstall the same driver through Nvidia without that same problem. Idk where to go next with this tbh, please feel free to throw any suggestions out, thanks.

Specs: 13900k (no oc) 16GB fury 4800 (ik it’s slow but I’ve used this build for a year, ram ain’t it lol) Asus z690 hero Nhd15 cooler 970EVO Corsair 680x case 3080 FE (no oc either) Corsair 1050w PSU Monitor 1 Samsung crg9 Monitor 2 is some generic dell 1080p

Thanks again guys
