Windows 2000. ASUS A7A 266 motherboard. Bios version is dated 3-27-01, current but there is an update available. Wake on LAN disabled, wake on power loss disabled, wake on anything is disabled in the BIOS. This PC turns on (after a normal shut down in windows) anywhere from immediately to 30 minutes later. Now, if you kill the power supply to the PC for a couple seconds and then turn the power supply back to the on position, the PC does NOT turn on unless you hit the power switch. This is the 3rd motherboard i have had on this power supply, this is the only time i have encountered this problem (300 watt powermax). I am working on getting an altenate power supply to to try it, but by "resetting" the power supply it leads me to believe that the power supply may be fine. Really don't want to flash the BIOS (its a pain in win 2000). Anybody expierence this type on issue before?
