Lately, I've been having a rather annoying computer problem. You see, every so often (and by every so often, I mean way, way too often), my monitor will just cut to black, claiming "No signal on DVI1", meaning it's no longer receiving any video output from my graphics card. Now, sometimes, this just seems to happen by itself, but other times, it happens at the very moment that I accidentally bump my rig (physically) or drop something on the floor or do something that might jostle my computer in some way. And it's not just the video card that cuts out; everything else on my rig does, too, apparently (I can't activate, say, Num Lock on my USB keyboard, and my sound cuts out, as does my network connectivity). Still, the computer's technically on throughout all of this- the fans are running, the lights are on, and (occasionally) I can see the HDD activity lights blinking, too.
So, my best guess is that there's a faulty wire in there somewhere, likely in the PSU (in the 24-pin ATX cable that connects to the motherboard, maybe?), but it could just as easily be something in the motherboard itself, and that's something I really don't want to have to pay for right now. Has anyone else dealt with something like this before? Veteran wisdom would be mucho appreciado.
