I'm having a strange problem. When I leave my PC turned off for a bit and then try to start it up, the on/off switch on the front of the case is non-responsive. I have to hit the CLR CMOS switch several times, after each time the LCD poster gets to VGA BIOS and then the system stops. Eventually I can get the video to come up again, go into the bios, restore my settings and everything is back to normal. This has only happened twice so I wouldn't call it a pattern just yet, but it's happened the past two times that I've shut the computer down overnight. I don't know whether to attribute it to BIOS 903 or not. Would love any ideas.
