Monitor showing "No signal" after a random time

post #1 of 4
Thread Starter 
Hello guys,
I have a problem with my monitor/video card and I don't know why.

When I'm using my PC, suddenly my monitor stops working and shows "No signal" after a random time (no matter what I'm doing), and I'm forced to reboot my PC. When I do it everything work well, until I get another time that error. Sometimes it happens after two minutes, sometimes it happens after three hours... it is just random.

I have 358.87 NVIDIA drivers, my videocard is a Gigabyte GTX 980 Ti and I'm connected to monitor via DisplayPort. My monitor is an Acer XB270HU.
I tried to change the DisplayPort and to return back to previous drivers version but nothing changed.

What is the problem?

Thanks for the help!

Hi there rolleyes.gif

Well the logical steps to check are:
  1. See is if the drivers are giving you problems, try installing a non beta drivers with a clean install.
  2. Check if the output of the GPU is the one giving you the problem. Verify each of the ports of the cards,
  3. You can double check using another cable and see if that helps, it's rare but maybe is something wrong with the cable.

I don't want to make assumptions but since you already did almost all those things, If the problems still persist after this looks like you may have a faulty GPU thumbsdownsmileyanim.gif

There is another option, in which maybe you monitor is faulty, and is stopping in receiving signal. Im not sure if this is even common with yours, but you can try connecting other things to the screen and leave it on and see if it turns off. But i think it's all good with yours.

I don't know if you reinstalled the latest stable drivers (not the beta) to verify, but if you are going to repeat the process, be sure to do it with a clean driver install, meaning that there are no traces of the other driver, you can do this by using a Display Driver Uninstaller. you can use this one if you want Display Driver Uninstaller

I hope that helps rolleyes.gif

  • I tried another driver version;
  • I tried to switch between the 3 DisplayPort input of my GPU;
  • I don't have another DP cable, but... can the problem be the cable?

I also tried to format and make a clean install of Windows 10, but with no results...

I really don't know which is the problem.

Well is not likely but it can be. If the cable is broken inside maybe with a sudden move it makes you lose signal, but i dont think that's your case. If you have a DVI cable, you could also test the other 2 ports and verify if you still have the same problem. rolleyes.gif

If you are using stable drivers, with a new installation, then to me sounds like you have a faulty card, maybe are the vram that are giving you trouble.

Are you OCing the card? or are you running stock clocks?
