I built my PC back in January, and just recently it refuses to boot. Whenever I turn on the power, the case fans and LEDs turn on for about a half-second, then turn off, then attempt again, then stop. This has never happened before, and the only diagnostic that I can see is the CPU-LED light that flashes when I turn it on. I tried remounting and reinstalling the CPU fan, but it did nothing. My system specs are:
ASUS P8P67 Deluxe
Intel Core i5 2500k
ASUS GTX 560 Ti
Corsair 8gb Vengeance RAM
Corsair 750w Professional Series
Cooler Master 690 II
I'm praying that this doesn't mean that the PSU or motherboard is fried.
