As stated, my suspicion was that my PSU failed suddenly last week. My girlfriend was typing a paper for school when we heard a "POP" come from my case, followed by sudden shutdown. No response whatsoever power-wise. So I ordered a sweet new Seasonic 330W PSU from Newegg and put it in myself when it came. After having hooked it up, I get no case LEDs, no case fans, no response whatsoever other than when I turn the I/O switch on on the new PSU, the green LED comes on on my Motherboard. Being that I can't find my motherboard manual, and I can't find the LED trouble codes on the Asus website, what do you guys think my problem is? My Motherboard is an Asus P4P800 Deluxe. The LED is flashing at a constant rate when I turn the power on, probably once every second or a little less. HELP!
