Monitor Losing Signal Intermittently on 780

[Centurius]

Hey All,

 

So for the past few weeks I have been having a weird issue every now and then where my screen will go black and completely lose signal for a few seconds on my GTX 780. I have managed to rule out both the monitor and cable themselves by trying them out on the iGPU which works just fine. 

 

There doesn't really seem to be a pattern as it will happen independent of workload or any specific time. To illustrate, I played the Mass Effect Andromeda demo for about 6 hours at once yesterday and had 0 issues while earlier this afternoon it happened when just watching a show in Plex. This also leads me to believe it isn't PSU related(I had that issue before but then the GPU only turned black on high load and the system shut down entirely). I'm running the 378.78 driver right now but it also happened before that one so it seems unlikely it's a driver related error.

 

If any of you have any ideas what might be causing this and if it's fixable I'd love to know. Otherwise even though the problem is incredibly hard to reproduce I may rma it just to be sure as the 3-year warranty on the GPU ends a month from now.

Have you (or rather, can you) tested if the issue occurs using another monitor with your 780?

Forgot to mention it in the OP, but yes I've tried it using my gf's monitor. It didn't happen there though it is possible I didn't leave it on long enough(there was nearly 24 hours between the last two events whereas I tried the other monitor for 12 hours).

Hmm.

I mean I guess it wouldn't kill to give it one other go. Might just be something with your GPU and current monitor, though.

At idle, does your card actually idle? What os?

Thanks, I'll do that.

Yeah, it clocks down to 324Mhz and about 39 celsius. Windows 10 Education 64 Bit
