For the past six months or so, I've had to vacuum out the case every month or two or else the bluescreening starts up again. Annoying, yes, but manageable.
The most recent time it bluescreened, I went and got the vacuum, and cleaned out the case as usual. However, the computer then started crashing in a way I hadn't seen before:
Seemingly randomly, the screen will lock up, the speakers will emit a loud buzzing sound, and I will be forced to hard reboot the machine. No BSOD, no minidump to debug the problem, just a frozen computer. All the fans keep running normally. This occurs about once or twice a day, and has been going on for the past three days or so.
I have a nagging suspicion this is a problem with my video card (nvidia 8800 gts g92), as the last bluescreen before I vacuumed out the case was the following error:
THREAD_STUCK_IN_DEVICE_DRIVER caused by nv4_dsp.dll (nvidia display drivers). I think it's a hardware issue, as I haven't made any software changes to my video drivers in a looooooooooooooooooooong time (I can't update from driver version 180.48 because nvidia hasn't fixed the bug that kills dvi output on some of the older cards yet). 99% of the bluescreens I had seen before were page faults, which were most likely caused by overheating RAM from the information I could gather.
The card isn't overheating (most of the crashes occur when it's not under much stress, around 75 degrees). My CPU temps are fine, as well: 52 degrees according to the BIOS.
Eventviewer shows absolutely nothing going wrong prior to the crashes, and, as mentioned earlier, I have no minidump files because there's no bluescreen.
Any suggestions on what this could be, or how I could go about fixing it? I'd really rather not RMA my video card before I'm 100% sure that will fix the problem.
