Hi everyone, I recently replaced my AMD Radeon HD4870 with an nVIDIA GTX560 and at the same time bought a Seagate ST2000VX000 2TB. I downloaded the latest drivers (320.49) and installed them. Since then my computer would just randomly restart as in completely restart, I will not see a BSOD, it would just start to boot from the BIOS again. However when I log back into windows it gives me a message telling me that there had been a crash (BSOD) even though I did not see any blue screen of death. I've tested my RAM - 100%, I've run Intel's Linpack - 100% and I've run furmark on the GPU and 100% no crashes. This only happens when the system is in idle. I also have Windows XP and I've used it the whole day without it happening once. My question is where do I start tracing the problem because the Event log doesn't really tell me much it only gives a motherly long memory address and that's about it?
