Computer screen goes to no signal randomly

[River]

Out of the blue my whole computer monitor screen goes black then says no signal. Why? What could be the issue?

It can happen at any time.

Demanding and not demanding times.

Also my fans go really fast or spin really fast after the screen goes black and says no signal

I do you a pcie riser cable / extender for my gpu. Did read those can cause issues but never had it happen previously when using it.

This is not a fun issue to deal with. Ask me how I know.

This is usually the graphics card "panicking" when the fans go full speed. I'm presuming you've already monitored temperatures to rule those out? Tried different display cables (either DP or HDMI)?

If anything is overclocked, stop and set it back to stock for troubleshooting purposes. This includes any RAM profiles like XMP for now.

What happens after the display loses signal? Does it stay that way permanently requiring a force shutdown? Or does it restart on its own?

If it does the latter, does the power ever cut out during this process or no? Freezing is one thing, restarting is one thing, and power cutting off is yet another thing and they all might be clues to narrow it down.

If sound is occurring before the loss of signal, what happens to it? Does it keep playing for a bit like the PC hasn't yet fully crashed?

Since you're using a riser, the first few things I'd suggest is to try without it. Alternatively, if you're willing, see if your motherboard has a setting for the PCI Express generation and try lowering it. You might also have poor contact between the graphics card and motheroard (with or without the PCI Express extender) causing it to intermittently lose contact with a particular trace during heating/cooling cycles. This one is something that someone else with this issue had and I'm now wondering if it's what my own similar issue may have been all along. So maybe try with the PC resting on its side or with the support bracket (if any) set to have the graphics card in a slightly different angle.

Beyond all of this, you also need to look for logs. They will possibly hold clues if they exist.

Check event viewer.

Check the Windows/Minidump directory for BSOD logs.

Check the Windows/LiveKernelReports/WHEA and Windows/LiveKernelReports/WATCHDOG directories. Any files in either that correspond to the time of the issue? If so, you can use WinDbg to open and analyze them.

go into device manager/display adapters uninstall and let it reinstall itself then reinstall gpu drivers.if you want to can do it in safe mode then restart

bad cable maybe?

or is the display losing power?
does its power light turn off/on?

Stays that way and requires a forced shutdown

And about the rest?

If it's not shutting down, then that seems to rule out that anything like OCP, OTP, OVP (basically all the PSU protection stuff) or any other similar motherboard-side protection. It doesn't entirely rule out the PSU, but it might take it away from being the top suspect.

Would need follow up on the rest to further advise but basically you need to be looking at logs, and doing other basic precautions. Here that would mean ensuring temperatures are fine, undoing any and all overclocks to see if that changes things, might as well revert all BIOS options to defaults, checking connections and possibly reseating stuff (which in this case includes removing the riser from the equation), trying alternate display cables, and you could reinstall the graphics drivers if you want to remove doubt on those. See if there's BIOS updates too.

Also, might not hurt to provide a CPU-Z for reference in case it's needed later. Hardware information is basic stuff to provide for these sorts of threads.

If you're lucky, it's just a loose cable or driver misbehaving.

can also be a bad hdmi/dp port on the gpu or display

linus did a thing with a gpu across the room from its pc, using extensions, and another psu for the gpu

extensions dont cause problems

Display Driver crashing would be my guess.

While I say yea, most likely it can also be the Display cable and/or Riser Card. Especially of its the riser card cause if that's faulty or poor connection the system basically thinks the GPU has been removed while the system was running. Your not going to get a picture to come back if that's the case, not without a system reboot

[macatak]

might be a gpu issue

Ok I could still hear a game on my computer after the computer screen goes to no signal randomly.


So thinking it is the video card or riser



Though right now after testing my old backup video card no issues so far.

As i said, display driver crashing and failing to recover, the PC wouldnt still be operational if it was an issue with the GPU itself after the display crashes.

If its the riser are you not able to just remove the riser and test the GPU directly?

Can't.

This is my case. https://www.newegg.com/p/N82E16811112559?Item=N82E16811112559

The PC has no more picture. How is it operational ? Just asking.

I will try to remote desktop into the pc next time it happens. If it does.
