Ive recently been getting BSOD's after anywhere from 1-6 hours following boot. This usually happens when Im running games (Skyrim mainly), though I had one today where I was just on the desktop.
the first 4 came under the bug check name 'WHEA_UNCORRECTABLE_ERROR' and were suspected to have stemmed from 'hal.dll' the last one (the one that happened whilst on the desktop) came under 'IRQL_NOT_LESS_OR_EQUAL' and stemmed from 'ntsoskrnl.exe'
GPU Idle temp: 39-41
CPU idle: 38-45
Im using Nvidia's latest 295.73 drivers, and experienced BSOD's both using these and the ones prior.
My mobo, cpu and ram came as bundle that was professionally over-clocked from scan.co.uk, and they stress test it for 12 hours several times, and 2 days ago, I left my PC on for 25 hours for a download and it didnt BSOD once
The only other thing I have seen cause those types of BSoD is the HDD, but a Corsair SSD going bad? Unless you are consitently writing to it, I doubt it. But running a hardware test on the HDD/SSD wouldn't hurt as well.
