I built a new PC for myself with a P5K Deluxe, 2GB Crucial Ballistix, E6400, eVGA 7900GS, and Vista Home Premium and so far it has been working out great. However, occasionally, if I let the the computer sleep or go idle for a long time, it won't let me restart normally. I move the mouse or press the keyboard and everything seems to start up including the fans, power LED on the case, and the lights on the keyboard but I get no video at all and possibly and it is totally unresponsive. Does anyone happen to know what is going on?
