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.

It can be so many things but start by trying one ram stick at a time.
I just tried reseating the RAM sticks and it worked. Thanks for the advice.
