I built a machine about a year ago (1GHZ tbird, FIC AD11 mobo). For almost that whole time now, it will not shut down automatically. When I use the shut down command, it either shuts down (past the "now safe to turn off your computer screen) but does not turn off, or it reboots. Just pressing the power button does nothing. Holding it for several seconds sometimes shuts it off, sometimes reboots it. So I usually use the switch on the UPS
I'm running Win2K and have reinstalled it several times during the year, no change in behavior. I also tried installing win98 at one point; it did the same thing. I've replaced the PS, still no change. I'm guessing there's a mobo problem. Any ideas short of replacing it? Could I have something wired wrong?
