I put this PC together a bit over a year ago now, has never given me any issues.
I was just grabbing a new tag in Whitegate when my computer froze solid. Powered it off, turned it back on and it wouldnt even post. No beep, no error beeps, no signal to monitor. Fans are spinning and lights are flashing fine (Single rail power supply so I doubt that is the issue). Unfortunately my motherboard doesn't have diagnostic LEDs..
I took everything off the motherboard, reseated everything with no change. Tried to boot with only cpu, memory and video card with no change. Reset the CMOS for lulz and that didn't help. The PC I'm on now is rather elderly so I can't swap even video cards or memory to test, but I seriously doubt either is the issue.
I wouldn't mind a second opinion before I hand my christmas shopping damaged credit card over to newegg for new parts.
