Weird crashes and symptoms.

[cravingsleep]

Occasionally my computer will crash, black screen, and the GPU fan sounds like it speeds up to 100%. (Don't know about other fans since there all at 100% anyway. My GPU temps. are fine (within the 40-60C range).
This seems to be happening when the PC is on idle as well.

Any suggestions?

Thanks,

Since it is VERY random sounding... Could be a few things... Bad PSU, bad RAM, bad motherboard.... What are your voltages? If needed, use HWMonitor at cpuid.com, don't download "pro" get the regular one.

If voltages check out as good, then run memtest86 overnight on your system, letting it get several runs. Also, PC specs would be helpful.
