Computer won't turn off

My Main PC (see sig) will not turn off.

When I shut down the PC in Windows everything exits normally. My screens go black and then into sleep mode like normal. However the computer does not turn off, it remains on.

This problem began when I upgraded from BOIS 1008 to 1016. I've tried several BIOS Power settings with no success. Could it be Windows?

Yesterday I upgraded to the latest beta BIOS (1017) and the computer still will not turn off.

How can I get my computer to fully shut down?
 
Assuming you dont have a broken mobo, windows' power management settings profile probably got changed when the bios was changed.
Make sure you enable advanced power management within windows maybe that will work.
Otherwise, you may need to repair windows install, assuming hardware is fine.

How can I enable Advanced Power Management? I went under Power Options and it's not there.

 
If its not that I found a couple NIC cards and 56k modems that wont let the computer completely shut off... even with wake on lan turned off.

It's not either of those items. Any other ideas to help my PC power down?
 
When flashing bios did you first clear CMOS?

I'd try that again.
-First ground yourself, then
--move your motherboard's "clear CMOS" jumper to its "clear" position.
---Now pop out the cmos button battery, and
----physically disconnect the main power cable from the back of the case, and
-----press the computer's main power-on/off button on the case front a couple of times to help drain capacitors.

Let it sit like that a long time. Most people say for a couple of minutes, but I say, based on an experience, to let it sit like that overnight, i'e. many hours.

Then put everything back, and reflash your bios during your first boot-up.

In case that doesn't fix you, then try this as a test:

-Within WIndows, Start\COntrol Panel\Power Options, Hybernate tab, remove the checkmark from 'Enable Hybernation."

--Copy this exactly & past it into Notepad:

%SystemRoot%\System32\shutdown.exe -s -t 05

---Save it somewhere with any name you like, taking care to save it with the file extension .bat instead of .txt.

----Now while you're in Windows, Start\Run and run the .bat file you just saved.

That ought to force complete shutdown including power-off.
 
Scott - thanks for your detailed reply.

I will try your clear CMOS instructions tonight.

I did go ahead and try your .bat solution. Unfortunately it didn't work. It did shut down the computer but it still will not power down.

I will update this post after I've tried your clear CMOS guide.
 
I have the same mobo (A8N-SLI Deluxe), and have the exact same problem... since I've flashed the BIOS to 1016. My PC will not completely shut down anymore. I'll be very interested to know what causes this and how to fix it.

Thanks.

Maybe if clearing CMOS & reflashing bios is not successful, you could ask your question on the Asus forum dedicated to A8N-SLI Deluxe.

SInce you two guys are experiencing the same problem, changces are many others are too.

Also, I see reference there to something called "the asusupdate tool." It may be worth looking into using that for your bios flashing. (It's hard to refrain from cracking a joke about an asses update tool)

I still lean toward thinking your problem will go away by thoroughly clearing CMOS & reflashing bios.

Last thing is to read through this: Text
 
Scott,

Thanks for your help.

I read the OCZ thread; thanks. Seems like they have great tech support (advance RMA - wow). I don't think it's the PSU because I've been using the same one since this problem started.

I tried your suggesting of reflashing the BIOS. I can't use the Asus tool in Windows - it says "you already have the latest BIOS."

I then broke out my old school floppy disk drive and hooked it up to flash it from DOS. When I did it said the same thing it did in Windows.

Do you know how I can flash back to an older BIOS with this mobo?
 
run the flashing program (in DOS) separately with a /? (i.e. flash /? ) after it. you will get a list of the command syntax and parameters for the flash program. There should be one parameter that says to do the flash regardless. So just edit the .bat file used for running the flash to include that parameter on the flash command line in the .BAT file (you can use Notepad or any text file editor to edit the .BAT file).

.bh.

That sounds like extreme overkill. All you should need to do is move the jumper to the clear position for 30 seconds or so. It's not gonna get any more clear (for lack of a better term) by leaving it for hrs.

Quick short out by 30 second clear jumper doesn't drain all the charge.

Long "clear" periods sometimes can even resurrect the apparently dead motherboards.

As I said, I made this recommendation on the basis of experience with this phenomenon.
