So I was playing around with the timings on my ram, started prime 95 and got a BSOD. Computer reset and now wont post, mouse and keyboard are not getting any power either. Just built the system about a week ago. I tried resetting the cmos, and using only one stick of ram at a time but still nothing. Any ideas (motherboard dead, power supply, ram?)
I wasnt getting any beeps out of the speakers but tried putting in the small speaker on the motherboard and was getting short continuous beeps, i looked it up in the manual and it said that it was a power issue. Shouldn't a 550 watt be good enough? I used the power supply calculator and it said 450 watt.
You may have corrupted your CMOS memory, move the CMOS memory clear jumper with the power disconnected (not just turned off). It is common to have to clear the CMOS after a failed overclocking attempt.
