System doesn't power down after shutdown?

[gridiron123]

I have to instead, go to the case, and manually hit the power button to turn it off. The motherboard is an MSI K8N Neo socket 939 that I just put together this weekend. I've read the msi book and poked around in cmos a bit but haven't found anything about changing the bios to make it power off. Any help appreciated.

In Device Manager, if you expand Computer, what type of computer does it think it is? Sounds to me like what happens when you've disabled ACPI in the BIOS prior to Windows setup. If that's the case, address that problem and reinstall Windows. You can force what HAL it'll use by pressing the F5 key where it is prompting you to press F6 if you have third-party storage drivers yadda yadda.

Under computer in device manager, it lists it as an MPS uniprocessor PC.

What is ACPI? Sorry.

When I installed XP, it went on a 74gb Raptor SATA drive, so I had to hit F6 and add the drivers for it on there. Was I suppose to do something else also?


EDIT:

I just checked in the bios, and I found an option called "APIC" that is enabled. Is that it?

APIC is not ACPI, nope. Look at page 3-17 of your manual, does it have Sleep State enabled in either S1 or S3 modes, and not disabled? I'm speculating a little, but I think that may be what needs enabling. Enable it for S3 and reinstall Windows, and press the F5 key and force the ACPI Uniprocessor PC kernel on it if you like.

I checked the manual and then the bios, S1 mode was enabled.

So you reccomend changing it to S3 mode, and then reinstalling windows? Do I need to format or is just a regular re-install OK?

Hmm, I could be on the wrong track then Since a Quick Format takes about 20 seconds, you might as well blow away the whole installation and start over. Strange that it's doing that... you could reset the BIOS to optomized defaults if you think you might've goofed a setting someplace in there.

I'll go ahead and reset the bios, and reinstall XP and see what happens next. Thanks for the help.

 

[gridiron123]

That seems to have fixed it. Now I just need to go back in and reinstall all my os updates, firmwares, hardware drivers, ect. Oh well, atleast it works now. Thanks alot, I really appreciate it.
