No matter how I turn the PC off or put it into sleep mode, it'll stay off for about 1-2 sec and then automatically turn itself back on. The "wake after power failure" and "wake on ____" settings in the BIOS are disabled. I tried updating the BIOS too. No luck. I've googled several times and can't find anything. It's an ASUS barebone system with a Pentium Dual Core and 32-bit Vista. Let me know what info you need to help solve this annoying problem. Thanks everyone...
 
Its nothing too worry about, its commonly know as double boot bug. My rig does it also and I have it from since 2006 august.
 
The problem is it belongs to somebody who whats to be able to shut their PC off when not in use and they don't want to have to switch it on and off every time they use it. Any fixes?
 
Oh... motherboard or powersupply... Its more likely to be the board. But you should check it with another powersupply first.
 
Could it be OS related at all? I bought the system from a fellow here and he never experienced the problem with XP installed. As soon as I got the system I installed Vista and immediately began experiencing the "bug". Could it be an OS issue or did something get a little roughed up in shipping?
 
If it is restarting after shutdown its highly unlikely. Also it could be the power switch on the case.

Well, if I power down, switch it off at the PSU, and then switch the PSU back on, it stays off until the button is pushed. If it were a button short you'd think it would power on automatically when the PSU is switched back on.
 
I have this same problem with an Intel BLKDG33TLM mobo. It will shutdown, completely power off, fans are hard drives spin down, and about 2-3 seconds later it comes back on. I was using as my HTPC, but decided to go with a Popcorn Hour instead. I retasked this mobo as my Untangle router/firewall box. That way it's on 24/7 anyway. I'd be interested in a solution if anybody finds one. BTW I was running Windows 7 when I was using it as an HTPC.
 
I've had the same problem on my current motherboard (an Asus P5E3 Deluxe Wi-Fi). It went away after a BIOS update. It's worth a try...

(Be careful if you plan to do that, though. If you're a casual user that's not comfortable with low-level changes to a PC like that, it's not for the faint of heart. You could render a PC dead with a failed BIOS update.)

you mean he could kill the motherboard. which he probably needs to replace anyways.

Out of everything, chances are it's the motherboard. Not likely an OS problem if its 1-2 seconds after shutdown. On the other hand, if it's just resetting itself (aka no delay to the restart), you could be having a shutdown problem - If vista BSOD's then it just reboots.
