That is a DIY computer right?
I'll be assuming that it is.
It may be time for a routine maintenance of the hardware, cleaning out things and reapplying TIM and whatnot. Monitor your CPU and chipset temperatures, it could be that your computer is overheating.
Do a stability test, OCCT on Linpack mode is a good stress test for stability, if it passes for 24hrs, then your CPU is stable, and that your RAM should be stable. I recommend doing a RAM test with Memtest86 afterward, though, for another 24hrs. It could also be a PSU problem, the PSU might not be supplying enough power to the rest of the system when under load. Should this be the problem, the aforementioned stability tests (especially OCCT on Linpack mode) will pick it up, assuming you don't have a dedicated GPU. If you have a dedicated GPU, try running the OCCT GPU test or Furmark AND OCCT on Linpack mode (this WILL lag like hell, your computer will probably barely respond to input, though if it stops outright, it probably crashed). Do NOT do anything else on the computer while stress tests are running, make sure no other applications are running.
If it's software related, it is probably a recently installed program and/or a virus, try uninstalling recently installed programs and doing a virus scan (please, not with Norton).
That's all I can think of at the moment.
