Hi everyone,

I built my first gaming PC a few months ago and things have been mostly okay until earlier this week.

All of a sudden, the computer just disconnects both monitors and everything goes dark. But the computer is still on. I can see the lights on my internal AIO cooler have not dimmed like the system rebooted. I’m sure the computer is still on despite there not being any video, but I don’t have a way to test since video out isn’t showing.

I checked my display settings and everything is set to “never” go to sleep or put the screen to black. I also updated to the latest GPU driver available and am now performing a clean reinstallation through GeForce Experience.

Despite this, it still happens. Tonight was worse as I was playing Starfield and the screen just went black and the fans started going really loud. From the sound of it, it was the fans on the front of my PC case, not the GPU fans.

I did some Googling and saw that others with the 4070 Ti recommended turning off G-Sync which I did, but issues persist.

My PC’s specs:

  • AMD Ryzen 5 5600X
  • MSI MPG B550 motherboard
  • Zotac Nvidia RTX 4070 Ti
  • 64 GB DDR4 RAM (x4 slots of 16 GB each)
  • Windows 11 x64 bit Pro

Not really sure what else could be going on. I’ve checked Event Viewer and a lot is getting logged, but nothing that seems immediately relevant to this issue. Anything specific I can name that might help with diagnosing? Tonight was the first time this happened during a game. Most occurrences have been while the computer is idle on the Windows desktop.

    Sounds like it might be a hardware issue. I’ve experienced this exact thing as well and I use Linux. I believe I had a loose pin in one of my power cords but I’m not entirely certain because it was handled by a tech repair store. Check if you GPU fans are spinning a little after the video cuts. Eventually mine actually complete stopped working.

    I ran into this. Let me guess: you updated nvidia drivers pretty recently. Nvidia’s driver update process seems prone to introducing some amount of dll version mismatches or corruption and it’s not as rare as you’d think. Not really sure why nobody ever seems to talk about it.

    Try using DDU to completely uninstall your nvidia drivers, making sure to go into its settings to disable Windows automated driver download to be safe. Afterward, install the latest drivers downloaded from nvidia.com. That should hopefully resolve your issue like it has for me.

    Not sure how to edit this on Memmy, so I’ll add a comment.

    Appreciate all the suggestions here from everyone! I tried them but had no luck.

    I think I had my GPU fail on me.

    I think either it was a bad batch. The guy at the store tonight told me stories of other customers who have had some bad GPU issues from new GPUs, which makes me think maybe production has been crappier than usual lately and I got unlucky?

    Second thing I think may have happened is I cheaped out on a PSU and I shouldn’t have. It had decent reviews on Amazon, but I should have shelled out the extra $10+ for a name brand PSU with some years behind it and dozens more reviews and a bigger company to back it. Idk, maybe.

    So I ended up replacing my PSU with a name brand PSU and also returned the 4070 Ti under the extended warranty. The store I got it from actually let me basically get store credit, so I put down some extras for a beefier GPU from AMD.

    I got everything set up tonight and have been using it for a little over an hour with no issues so far. Thinking the GPU was the culprit. I also put on a new dose of thermal paste for the CPU and did some cleaning during the installation, but don’t think that was really needed or contributed to this, but figured I’d throw it out here for anyone who happens to find this in the future.
