I scanned the list of forums, but couldn't find anywhere else to put this. I put it here because while I've seen a Windows machine crash more times than I can count, I've never seen it crash and then, seconds later, drop the video card.
This has happened twice in the last couple weeks. The first time, from the desktop, the computer halted, sat for a few seconds, and then the monitor went into power-saving mode (no signal) while the machine was still on. The second time, it happened during a full-screen video game. It hung for a little while, and then the screen started puking unpleasant white noise through its pixels. These were both hard crashes, no CTRL-ALT-DEL or anything, the only fix was a hard shutdown, after which the computer booted fine both times. The Event Viewer shows the kernel-power warnings that come with a computer booting after an unexpected shutdown, but there's no warning or error before the machine stops responding.
I'm beginning to be concerned that I have a hardware problem. I don't think it's heat related, I'm moderately overclocked on the CPU, but also water-cooled, and rarely see temps higher than 40c. My video cards are at stock clock and rarely top 60c.
Does anyone have any insight into this? Or, if a mod decides this might be better elsewhere, can you move my thread there? =)
