I happened to just be web-browsing when my monitor goes black and reports "no DVI signal" before powering into standby mode, as it does when I shut down my machine.
As my computer was still running, I tried plugging the DVI cable in and out of the port on the video card to no avail. Then, I decided to test the monitor and cable by attaching them to the DVI output on a spare laptop. The monitor came back to life.
So I am fairly certain that my video card [actually 2 GTX 680 cards in SLI] suddenly stopped outputting a DVI signal for no apparent reason.
I ended up shutting the computer down [improperly since I couldn't think of a good way to shutdown without being able to see the Windows desktop]. I decided to restart my machine with the monitor attached to see if I would get any video output. I was pleasantly surprised to find that all appears to be back to normal.
But of course I'm concerned that this happened at all... This is the first time anything like this has happened, and I've had the machine for the last year and a half. I installed the latest nVidia GeForce driver some days ago without incident. And I don't think there was much stress on the video cards since I was just browsing the web when this occurred.
So, with all of that said, what would you do to avoid this problem recurring? Feel free to give me the bad news, even if that happens to be that my video cards are definitely failing and I'll need to replace them. I'd rather have some educated guesses as to what caused the problem, than no idea. And right now I'm pretty baffled by this.
Thanks!
