A couple days ago, my computer began to consistently BSOD within a few minutes of startup. There have been no recent hardware or software changes that I can think of. The computer was off for about 3 days prior to this. In the past, I've had intermittent bluescreen errors, generally only once, also shortly after startup, if at all.
Thus far, I have run Memtest86+ for over 12 hours (9 passes) with no errors. I have not done individual stick testing, due to the memory being difficult to access (CPU cooler extends over the sockets). I have attempted to to a repair install of Win7, but a stop occurs before it can complete. Prime95 will have a fatal error with ~15 minutes or so, but I was able to run it in safe mode without a BSOD (I'm generally more stable in Safe Mode, as I am now typing this). I have upgraded my video drivers. Driver Verifier tends to cause faster failures, but I have not been able to get a dump from that. I am not overclocked, though I have slightly increased the voltages to my memory and processor, with no notable effect on the crashes.

I have attempted to capture a dump from a Driver Verifier crash, and have not been able to, even after following the instructions here.
My C: drive is limited in space (60GB SSD), so I thought that may be the problem. I changed the dump file location to a different drive, still no luck (the page file is still on C:, I did not change that, though I attempted to increase the size, as it was warning about it being too small for error reporting). Although, the blue screen stays up noticeably longer once I changed settings. It seems like it is writing the dump somewhere. I don't run ccleaner, could antivirus/antispyware do something similar? (like Avira or Malwarebytes?) I don't even get minidumps. The most recent one is from 6/17 and I've crashed a couple times yesterday and today.
I also had intended to add that I ran chkdsk on all drives with no problems, and that SpeedFan reports my temps as well within safe range (<55C under Prime95).
