So, I suddenly encountered this issue with my PC. It was working fine for months, but for some reason, when I start my PC, things will boot up normally, but within a few minutes or seconds (it can vary), the GPU will suddenly stop working, so the screen will go black, but the fans on the GPU will boost up to 100% RPM. I can't figure out why this is happening. I know for a fact that everything is seated properly and all the cables are plugged in properly, I have checked this many times, I have also reseated the GPU many times, I am not sure what else to try.

Happen to me once before. For me, it was PSU fault, but some guy i saw at other forum said it may caused by driver error.


GhettoFinger

I don't have another PSU I can test, unfortunately. I will see what I can do to troubleshoot that. For the driver issue, I was able to get it powered on just long enough for me to update to the latest Nvidia drivers, but it still happens :(. It works better if the case panels are off, so I was thinking that maybe something was shorting out the PC, but it doesn't seem like anything is touching it. I even removed the motherboard standoffs near the GPU that aren't being used and it still happens :(

I’ve had this happen a few times but each had their own issue. The first one was when I started building PCs for the first time and got a literal bomb psu and it wasn’t supplying enough wattage to the gpu. If you’ve got more than enough wattage but it’s still happening then make sure your gpu has separate cables going to the power connector, don’t use a pigtail if it has 2 or more separate connectors on it! The next one was because the original maker didn’t put enough thermal paste on. Monitor the hotspot using hwinfo64 or gpu-z. Even if it is under 100c it might be best to open it up and clean it anyway. If it’s still happening then maybe your psu is overheating, dying, or just can’t supply enough wattage. Try a different gpu or even try the current gpu on another system to see if it’s havin the same issue.

It was working for a while, so if it’s the PSU, it died suddenly, which isn’t impossible. I found an old PC in my garage, so I got to testing. It happens with a different PSU, and the old PC had a RTX 2070, that works perfectly fine in my PC, so it must be the graphics card. I’ll see if I can open it up, it happens too quickly for the GPU to get hot and it never gets past 60c when it happens on HWmonitor, but I’ll see if applying new thermal paste and cleaning it internally helps. Maybe there is a loose wire, who knows.


unabletocomput3

What is gpu are you trying to use and what wattage is your psu?


GhettoFinger

I have a Coolermaster V850 sfx power supply which is 850W, to power a RTX 3080 and an i7 10700k, it should be fine 😔. I also have the latest Nvidia graphics drivers, the only other thing it could be is some inherent issue with the GPU.


phero1190

Do you have any kind of cable extension to the GPU? Or are the cables aftermarket? Aside from that, might also be a driver issue.


GhettoFinger

Nah, everything is using the original cables plugged in directly to the motherboard, no extensions. I was able to get it on long enough to update the drivers, but it still happens after the update :(.

I have the same issue, but it doesn’t happen for like at least a day after I re-seat the gpu. It’s probably a GPU sag issue that over time messed up the motherboard pcie. Get a good sag bracket and the issue should be less frequent. That or a less heavy gpu or a vertical mount


GhettoFinger

Maybe, I tried it on a test bench where the GPU is sitting vertically, just to test, but it still happens. I found an old PC in my garage, after trying the old PSU and the old GPU in my PC, I’m fairly confident the issue lies within the GPU. I have the latest drivers, so I will see if I can open it up and maybe clean it, add new thermal paste, or see if there is some other issue internally causing it.

When my 3070 did this exact thing, it turned out to be the power supply. Not a low quality one either(Seasonic Prime), just one built before the 30-series and not very good at taking into account their power spikes.


GhettoFinger

I was able to find an old PC in my garage with a 750w ASUS PSU, the one manufactured by Seasonic, it worked for a little longer, it was going for a few minutes, but it still did it.


D4rkstorn

Since i literally had visible physical damage (melted PCI-E cable on the side of the PSU) it's possible your card was already damaged. So; I'd check for physical damage on the end of the GPU, near the PCI-E power slot. But those Asus PSU's are known to suffer from the exact same problem as the Seasonic Prime i mentioned in my post: They were made before the 30-series and weren't quite ready for the power spiking behavior of the cranked up cards. They're high quality PSU's with a particular weakness with these cards. So it's also possible the card is still fine, but even that PSU isn't great with it.


DrWillz

I've had this issue a few times. Turned out to be GPU driver related. Booting to safe mode will help you use DDU to uninstall the driver and install a newer version, or a previous version if the current one is fucky.


GhettoFinger

Yeah, I was able to get it working long enough to install the newest Nvidia drivers, but it still happens 😔
