Windows 7: Microsoft ACPI-Compliant System driver missing W7 64

Hello,
I have a problem with the new build, PC doesn't wake up from sleep,
I tried everything you can possibly think about and I narrowed it down to
my last chance: in device manager I see un unknown device,
is the Microsoft ACPI-Compliant System driver that is missing.

I tried downloading the Asus (mobo is Asus H81M-K) ATK pack which should've been
enough to fix it but it didn't the Microsoft ACPI-Compliant System driver is missing,
hence my question:

where can I find Microsoft ACPI-Compliant System driver for Windows 7 64 bit?
Windows auto search for drivers didn't find it, Intel Driver utility didn't find it either
So I'm lost

everything I read redirect to problems with laptops and they all have their fix
on the manufacturer site, but this is a desktop and so...

any help will be much appreciated.
thank you!

Hi .. Select the Device right click select Property's / Details Tab ... Are there any PCI VEN numbers there ? ...

hi,

go here and under utilities try the eighth one down in the list. Motherboards - H81M-E - ASUS

Hey guys,
thank you for your help

So I downloaded and tried to install the application in the link
oscer1 posted, I tried to make the device recognize the path and auto
install, i tried installing manually, i tried uninstalling the device then installing manually, reboot each attempt and I get the same error every time, which is:

"Windows found driver software for your device but encountered an error
while attempting to install it.

AMDA00 Interface

The service cannot be started, either because it is disabled or because
it has no enabled devices associated with it.

If you know the manufacturer of your device, you can visit bla bla bla.."

So, yeah, no luck.

@Maxie
details tab, hw IDs only shows this:

ACPI\PNP0A0A
*PNP0A0A

EDIT: also just run sfc scannow just to check and
no errors whatsoever here found. Install was clean, new build, just few weeks ago

Seems you need the ASUS Probe from the Motherboards Website

Probe just installed, device still showing as driver is missing

According to few posts I read around it seems the Asus AMD00A is faulty

what if I disable that device? would it cause problems? Would it solve anything?

Can not see it causing any problems .. .. Read the Link below ..


Asus z87 Unknown Device in Device Manager: ACPI\PNP0A0A - Page 2

Ok so, it did the same thing, moved from other devices, to system devices
and up till here it was showing driver not installed, then manually reinstalled the Probe,
restarted and now it still sees it as unknown device (in system devices) but now
driver is installed, no yellow "?" warnings no more.

Thank you a lot, I don't know if this will fix the problem with the PC not waking
up from sleep but if not I know this is not the problem :)

(if that problem is not solved, since I literally tried everything the last one is
my monitor doesn't have 64 bit drivers, so I'll try another monitor and/or the DVI
instead of the VGA connection)

thank you so much for your help, really!

Most welcome :)

good job
