Faulty GPU or PSU? help please :(

 Share

Hi, earlier today while gaming, my GPU suddenly stopped outputting anything to either of my displays. I could still hear the game I was playing, as well as my friends in discord. I tried the WIN+Ctrl+Shift+B combo to quick-reset graphics drivers but that did nothing. The only thing I was able to do was force-shutdown my PC by holding the power button down. When restarting, the display was working again. Since then, any time the computer is under any sort of moderate to high load, it will do the exact same thing. This has happened nearly a dozen times today while I've been trying to troubleshoot the issue. If it means anything, one of those times instead of no display output, it turned both of my monitors pure white (only once out of 10+ times).

 

I have taken everything in my PC apart trying to solve this. I have made sure everything is plugged in correctly, as well as reseating the GPU. I have checked all PSU connections. I have cleaned out any dust. It is definitely NOT an overheating issue - my temps will only get to 70-75 degrees when this happens, and I can mostly verify this by feel and I can say it doesn't seem like it's misreporting temperatures.

 

I did use NZXT CAM to under-clock the GPU once this started to happen, and although that did help for a while, it ended up crashing after about 20-30 mins of gameplay. When running Furmark, the GPU will crash after about 30 seconds to a minute. I have not had the GPU overclocked.

 

I am wondering if this seems like a GPU issue or a PSU issue, as I have looked around and some people are saying that it's possible the GPU may be receiving too little power under heavy load and then will crash.

 

I'm a bit all over the place with information at the moment, so sorry if it seems a bit random.

 

My GPU is an ASUS 3070 Dual OC 8GB, and my PSU is a Corsair CX750M. I have had this configuration for quite a while and never had any issues like this before, nor have I added anything that should increase power draw. I'm not sure if it's a clock speed issue with my GPU or that perhaps it isn't receiving enough power.

 

If anybody could advise me on what I should do to go about this that would be great. Thanks 🙂

 

Edit: I have also tried multiple different Game Ready Drivers, that did not solve the issue. This started out of nowhere - not right after any game updates, windows updates or driver updates. I was playing for many hours the days before with the exact same config and software and there were no issues.

Can you try the GPU in a different PC?

I am not allowed to have my PC specs in my signature.

The only other PC I have access to has a PSU that's only 400W so I don't think that would be enough to run the card under load unfortunately 😞

Does anything forbid to try the PSU too?

I did also think to try that; however, the other computer doesn't have much in it at all, so I feel as if I were to put my current PSU in that system and it WAS sending too little power for my current system, it would still be enough for the other system to run fine and I wouldn't see any issues. I could be wrong though.

So definitely not a PSU issue. The PSU you have is pretty low end, and not something I'd recommend with a 3070, but that's not a PSU issue. Try using DDU to uninstall the graphics drivers and reinstall them. If anything is overclocked (including XMP or motherboard auto overclocking), disable the overclocks. You could also try using a single stick of RAM at a time.

If someone is saying that sort of stuff, I recommend staying far away from them, as they clearly have no idea what they're talking about, and are not afraid to just spread random BS and waste everyone's time.

Thanks everybody for the help, it turned out to be a faulty PCI-E cable! Thankfully the cheapest part of the entire lineup hahaha. Thanks again!
