I recently added on a HT Claro Omega sound card, and I overclocked the CPU to 4.3Ghz @ 1.35 volts in bios, vdroop put that down to 1.3325, RAM was just a tad over the rated speed with 8-8-8-24 timings. Everything was perfectly stable for 48Hrs prime 95 running on all cores, temps stayed below 60C the whole time. Graphics card was OC'd a bit (850Mhz core, 2Ghz shader).
A few days ago my computer randomly shut off, like as if someone had pulled the plug on it or something, I assumed it was an issue with the circuits in the house or that I'd blown a breaker or something, so I just re-booted and went about my business, it happened twice more over the course of the past 2 days, I got slightly suspicious, so I plugged the computer into a different outlet, it then proceeded to do it's hard shutdown again, I checked the logs, found no errors from windows or any of my hardware. I was watching a livestream on Justin.tv just a couple of hours ago and it did it one last time, i went to go re-boot the system and nothing happened, blank screen, no HDD activity, no post, no nothing, just a little glowing memory error light...
For the past while I've been troubleshooting the problem and trying to find a solution, it seems that it's either the motherboard or the RAM, I'm not sure what was causing the hard shut downs, or if that was a symptom of the root problem, or the cause of the problem. If anyone with more experience with this problem could give me some help I'd be very grateful, any educated speculation would also be welcomed.
