The standby power LED is lit, but nothing happens when I hit the button apart from a click noise from the piezo buzzer, however when I unplug it from the wall the fans spin for a second.
I thought this might have something to do with the power supply but I have tried 3 and it didn't work. I ended up jumpering the supply, and while it turned on all of the diagnostic LEDs were red. Intel's manual makes no mention of this code.
I have tried swapping CPUs, RAM, PSU, Cleared CMOS, taking out expansion cards, everything.
Any ideas?
