Graphics card randomly stops giving a signal sometimes?

[marshedpotato]

I know this sounds really strange, but recently my graphics card will randomly stop giving a signal. The only way to get it to start again is to force my PC to restart.

My graphics card is a Gigabyte GTX 760 with 4GB of onboard memory. It has 2 DVI ports on it which are both connected to monitors.

Recently, when I'm just browsing the web, or watching Twitch streams, or playing games, or anything really, my monitors go black and display a "no signal" message. If I restart my computer they come back on, then in a couple of hours, days, however long, it will happen again. It's happened at some pretty annoying times and I'd like to stop it doing it if possible.

I know it's the graphics card and not the monitor because the card is connected to 2 monitors and they both stop getting a signal at exactly the same time. When this happens I've tried disconnecting the DVI cable and reconnecting but it doesnt pick up the monitors it just says no signal. Only restarting will make the card start giving a signal again.

Any advice would be much appreciated.

Many thanks

Brad

What are the card temps, and is it over clocked? also have you modified it in anyway? (BIOS Flash etc.) Is it happening under load? or at idling? It sounds like you make have an unstable overclock as I would find it to be an "annoying time" if I were gaming or rendering and the card locks up.

thanks very much for your response. i'm not sure what you would class under load, but i was playing league of legends when it happened last. honestly you could run league on a toaster though and i have pretty decent specs so i doubt the card was really trying. last time it happened i was browsing the web (only chrome open) so i'm pretty sure it doesn't only happen when under load.

i've never overclocked or anything like that, unless that's how it's shipped? i haven't modified it at all it's exactly how it came out of the box. oh and my card sits around 33-35 degrees normally, which i believe is normal? Apologies, I appreciate this is a very strange one.

Hmm, that sounds like a very normal card, with very normal use. It would seem then the power supply is suspect, however, we know this to be false, as 850 watts is plenty. Thus, I fell it may be a card problem, such a issue has been reported before for quite a few cards. So, it seems the card is failing or has a driver issue which is unlikely for Nvidia, how old is the card?

The card is about 18 months old now. But now that you mention the power supply, I've just had a thought.... the power supply is plugged into an extension lead. The 2 monitors are also plugged into this extension lead, and then that extension lead is plugged into another extension lead. That extension lead is then plugged into the wall. Could this potentially cause problems?

Every time you use an extension cord there's some loss of power stability.

Try plugging it in directly to the wall, if possible, and see if this issue persists.

Thanks for the suggestion. Just moved my computer into another room where it can be in range of a power socket. Will come back if it happens again. Thank you everybody

Just incase anyone has the same issue and stumbles across this thread, plugging my computer directly into the wall didn't solve it. I fixed it by removing my graphics card from the PCIE slot, and then pushing it back in again, making sure it was all the way in. Then I made sure the power cables were pushed on all the way on the graphics card end and the PSU end. Since doing this (2.5 months ago) it hasn't happened since.

Hey marshedpotato,

I have also experiencing the same problem and i do the same you do(by unplugging and plugging the card into PCI-E slot and also with the cables).
But it gives again the issue so i just reduced my clocks even from the defaults. But the issue persists so PLZ bro suggest some other solution. It is really annoying and i don't have a plan buying a new one in the near future.

The problem for me here was always power related. The GPU was not getting enough power from PSU because cables were not connected properly. Can I suggest that you check the PSU cables on both ends, on the PSU and into the GPU as well, also you should try your graphics card in another computer with a different power supply see if the problem persists there.

Bro my PSU (Corsair VS650) is non-modular but I can assure that cable on the GPU's end is firmly plugged.
But I will also try my GPU in another computer if the problem persists I will inform.
Also think what the problem might be

Thanks<3,

Jazab.
