I have a Biostar M7NCG 400 motherboard. Probably 90% of the time you hit the power button, all the fans and the hard drive start spinning, but no video. Doesn't post, beep, or anything. Hold the power switch to shut it all down, push it again to start it back up and BINGO, all works fine.
So in short.....Sometimes it boots up on the first try. If it doesn't boot on the first try, it ALWAYS boots on the second try.
Also for what it's worth, none of my usb ports work. 2 on board and 4 with a usb header. I have reinstalled a legit copy of XP, did all the updates and service paks and still nothing. Other then these two little problems, everything else is working great! Any ideas??
