So i went to a local computershow this past weekend, not looking to buy anything but i saw this Asus A7V8X board and had to have it. well it wouldn't work. the board didnt seem to get power, it would turn on for a few secs then stop. I thought maybe the case was shorting out the board somehow. so i moved it into another case and it's working now, the only problem is it wont shut off? this defenitly has to be a PSU issue. when you shut it down in windows it sounds like it wants to turn off but instead it just powers back up. Help!
