Lately, I've been having a rather annoying computer problem. You see, every so often (and by every so often, I mean really fucking 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 the other thing is that I have yet to determine whether any other normal computer activity takes place during one of these blackouts (i.e. if Windows continues to run as normal while the video output is borked). Actually, now that I think about it, all sound output is cut off when this happens, too, so that's something.
So, my best guess is that there's a faulty wire in there somewhere, likely in the PSU (in the 24-pin 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.
