Both of my screens randomly go black
Posted by Healthy_War_9084@reddit | buildapc | View on Reddit | 4 comments
I have no idea why it started, but everything was fine for a few months, I bought a pre build pc, I had 2 EVGA 1080 Ti FTW3, but one day I was just playing and both of my screens went black, mouse and keyboard worked, but no sound and visualization. I restarted my pc, and it started happening more often, sometimes my pc is silent and sometimes fans go full speed. I switched to one you instead of 2, replaced thermal paste on gpu, bought and new PSU, reconnected cables and gpu, still doesn’t properly work, I do have to note that pigtail gives me way more time to use my pc than separate, please help.

Which PSU did you buy?
What's the rest of your system specs?
Have you done a RAM test?
Have you updated your motherboard BIOs?
If your CPU has a built-in iGPU, have you tried running without any dedicated GPU?

I just found out that there’s a difference between PSU and PSU cable, what I meant is that I bought 2 different cables, but as for PSU block, I have EVGA supernova G3, either 750W or 850W Gold Model. As for other things I’m checking right now and I’ll provide you more information soon

Standard PSU cables rarely fail without very obvious damage, but it does sound like the power supply unit might be faulty.

sounds like a rough one. even with one gpu it still acting up points to a power delivery or gpu issue. the fact that using a pigtail cable makes it more stable is a big clue, probably the gpu isn’t getting consistent power
first thing i’d do is test the gpu in another pc if you can, or try a known working gpu in your pc. make sure you’re using the original cables from your psu, no adapters. also try booting with minimal setup one gpu, one ram stick, nothing extra to see if it posts
if it works fine in another pc then the problem is probably your motherboard or pci-e slot. if it fails there too then it’s likely the gpu itself
given the fans spinning full speed and black screens it’s almost certainly hardware, software fixes like drivers won’t help.
