Computer Won't Stay Off!

Hi all!

I am about at wits end when it comes to this computer. I just built it like last week, and everything runs beautifully about it; that is, except that the dang thing won't stay turned off! I tell it to shutdown, and it turns itself back on after about two or three seconds. Let me clarify: the computer itself does NOT randomly shutdown, nor am I having problems with sleep or hibernate (haven't used them yet).

Ok, so I have tried about everything on every help forum I've read from here to knittingforums.com. I have disable all wake events, including the ones in regards to network adapters. I have disabled automatic restart, and even fooled around in the BIOS, disabling all wake events. I've even flipped around between BIOS commanded and OS commanded event wakes in the BIOS. About the only thing I can do is log off of my user account, and then do a hard shutdown. Even did the thing where you specifically set what the power button does.

So... please help! I will be most gracious, and will give any more information if necessary. The only thing I have NOT done is flash the BIOS; it won't recognize the USB device I have the updated drivers on.

I will take you up on giving more information. Like filling in your system spec's in your user cp so we know what your system is to start with. Thank you and welcome to sevenforums. Fabe

LOL at knittingforums.com. It's important to maintain a sense of humour under adversity :)

I was half-way through mentally composing the "have you flashed your BIOS?" response when I read your last sentence. In a way, I think it's important that you overcome the USB device side issue because flashing the BIOS is an important step in these situations. The BIOS code controls much of the hardware-level power management and power state functionality, and bugs in the BIOS can easily manifest themselves in this way.

Otherwise, you might want to rip out as much non-essential hardware and then test again. Remove the mouse, all expansion boards you don't absolutely need to run the box, all HDDs except the boot/system partitions, all USB/firewire-connected devices... The point is to test whether the smallest-possible hardware configuration does the same thing. If not, then you start adding things one-by-one until the symptom comes back.

Maybe it's a simple matter of having "power on mouse" in the bios.

If the mouse is on a shiny surface it will detect light changes and think it's being moved.

I had this with my HTPC, with the mouse on a glass table and mouse power on enabled.
Disabling it solved it.

It's worth to check it out.

edit: also check in device manager if "allow this device to wake up...." is checked for the mouse.
Uncheck it.

Just thought I'd see if anyone else had anything to suggest? Anyone? Bueller?

Hi sjones39

DocBrrown you gave me thought.

May be your power or reset button jammed.

Just a thought.

have you by anychance connected the 2 little wires that go from the switch to the motherboard the wrong way round? Im sure you know the ones I mean - there are a set of them which light up the HDD light on the front panel etc. There should be 2 of them for power. Ive seen that done before now.
