IME, the most common causes of sudden Prime95 failure after an extended period of faultless operation are:
0. Unstable overclock of CPU or RAM.
1. Heat due to clogged/stopped CPU HSF.
2. Memory failure. Use Memtest86+ to verify.
3. Video driver bugs (primarily NVDIA); this has become much less likely than in years past, and is less likely than the first three.
4. Mainboard failure.
5. CPU failure.
