I went to switch on my Comp this morning, and....nothing! I had not done any recent modifications to it for a couple of weeks, and everything had been running smoothly. But now, nothing...almost nothing. If I turn the switch on the power supply off for a few seconds, then on again, I get a flash of power...the fan on my GF4200 moves a little and the LED on the mobo flashes "FF" for about a tenth of a second, then all goes dark. The PSU is an Antec TruPower 330 and the mobo is an EPoX 8rda+. Anyone have any ideas what to look for??
