PC Won't power off when shut down.

[Yeoman1000]

Okay, my PC has been doing this thing where it won't turn off after I've shut down windows. It's done this before, and I fixed it by moving the jumpers on the motherboard, because that resets the CMOS battery or something along those lines?

Well, it's being doing it occasionally for 2 months, and I left it alone because it was only quite rare that it wouldn't shut down. My system is over clocked slightly (2500k @4.0 ghz, asus P8P67). So, I figured I just needed to move the jumpers again, but since it wasn't a big problem, I left it alone.

Now just over a week ago, I installed a second hard drive in my system, a 2TB WD green, for storage. And since then, my pc has done the not turning off thing every time. I tried flashing the CMOS battery today, (moving the jumpers), only this time it hasn't fixed the problem?

Any thoughts?

You could compare Event Viewer events with last night and this mornings if you want to delve into that, and see if there are any differences (other than sleep mode, of course) but a fresh install would most likely fix it. It is a shame that many have to do this as a solution. Oh well, it's Windows, and I have had to do this several times on my machine.

I'm not too fussed. It's good to have a fresh start. This will be my first reinstall since I assembled my pc & did all the drivers. So, I'm sure reinstalling may get rid of some 'gremlins'.

Thanks for the help though!

Cool deal. Happy fresh install 😀

Okay. I did a fresh install a few days ago.
I did it Saturday, the powering down issue has been fixed. Only, now I'm having issues with BSOD's. I've had two today.

(I was having these just on the last few days before I re-installed windows too), but I was certain I knew how I had caused them (trying to update my chipset driver I believe).
I'm getting the IRQL_NOT_LESS_OR_EQUAL code. I've had a lot of trouble with BSOD's in the past, but eventually fixed them, I found it was down to not having the correct USB drivers.


The tragic thing is, from day one Jan 2012, I had all the wrong motherboard drivers installed on my pc. (Asus P8P67 as opposed to Asus P8P67 REV 3.1) - because I got them from the website rather than the disk, and the REV 3.1 page at the time wasn't showing in the P67 chipset list for motherboards. So, for months I had BSOD's, and I finally got them fixed this august (USB3 drivers from the disk).
I realised the drivers were all wrong when trying to update the motherboard bios in august...and wondered why it wouldn't take the bios update. I also realised in august that since day one, my system had been overclocked (thanks to the TPU switch).


But. Fresh install. Correct drivers from the correct asus motherboard page (Lan, USB, Audio, Chipset, Intel MEI) dunno if I need the MEI though. There's no bluetooth driver on the asus website...but luckily one on the disk (I noticed the 'unknown device' - bluetooth adapter in device manager after BSOD number 1. Thought it might fix it. Now I'm a bit puzzled though since I had another.

But yeah, a pretty disastrous experience with my first home built PC. So much went wrong (and on the plus side, so much wiser as a result), but now I'm genuinely stumped. I'm going to finish off some windows updates, and see if that makes a difference. I know I'll need to make a new thread, either here or perhaps on windowssevenforums (they helped me with bsod's before), but for now I'm just venting steam!

Dan,

No, shouldn't be a problem with SATA connections or power. I even looked at your Mobo manual for power management. There is one thing that you could check there and that is in APM. Make sure that the On power loss options (1st one) is set to power off. Might be irrelevant since you said this was happening intermittently.

Ok. Two more things to try.

First, go into Device Manager from the Control Panel and go to IEEE1394 Bus Controllers. For every instance (should be 1), right click on the device, go to Properties. Then in the power managment tab, select Allow computer to turn off to save power. If it doesn't work, just uncheck after reboot. I have read that these can cause shutdown problems.

Second, you said you were getting WMI errors. Try to disable that in services. Start -> type services in search bar -> find Windows Management instrumentation in the list -> right-click to properties -> Where is says Automatic, change to Disable.

registered here to let people know that disabling Management instrumentation did the trick here. Thank you so much!
