Computer randomly losing video

[Charly Leyequien]

Hi guys

 

I have this extremely bizarre situation, for a while now I have had the issue where randomly my PC will simply lose video, some times I can still get audio, say, from a game or a video I am watching, but I have no video in either of my screens; some times I just lose both, but the RGB in my case(RAM, MoBo, PSU) is still on, fans still running, the PC looks as if it is running fine.

 

I am beside myself because I have practically a new computer

 

At first I thought it was my installation, so I bought an MSI Spatium M.2 ssd and installed windows there, still had the issue

Then I thought "Maybe, considering the PC is on 15-16 hrs a day and I game 8-10 hrs a day(I work from home), the GPU is dying", so I got myself a 4090 a few weeks back, but the issue persisted, and got to a point where I would have to cold boot the computer as usual when this happened, then not even 1 minute into windows, and it would just loose image again, I tried clean installing the GPU drivers more than a few times, but that didn't solve the issue

 

I thought "Ok, maybe my PSU is dying, or not capable enough" so I got an Asus Thor one, 1200w, and it even has a screen, my PC never goes above 550w, but it still happened

 

I thought "The Motherboard", so I tried flashing the latest bios, it would fail every time even though I was using an old usb as advised, it just wouldn't work, so I got myself a Ryzen 9 7950x3d and an X670e-a MoBo, plus a corsair dominator platinum ddr5(32gb), and I thought the issue was solved, it had been a week and no issue... until today, I turned the computer on, checked Jira for any outstanding cases that needed my attention, and before a Meeting, I went to the toilet, only to find my computer with no video, but the MoBo still on as I mentioned before, had to cold boot.    This happened about 10 minutes after turning it on

 

I just can't get it, I have a practically new computer, technically, and the issue still happens, and the temps never go high, btw, as I have been checking them with HWinfo64, never even close to the "hot" threshold

 

Anyone has any advise?
