This started few minutes ago.
Only two things done prior to this problem.
Attempted to boot from a different clone drive.
DiskMgmt.msc showed booted from Primary Drive NOT other.
With this MOBO, have never been able to boot from other than Primary when two clone drives
(same signature) in system. Was following some ASUS Tech recommendations which did Not work.
Prior to (1) did a Windows Update Definition Update.
Approx. time update 9/8/2017 10:15:00 PM EST
Looked in Windows Updates to see if I could Delete / Reverse.
NO Window Updates show for this time period.

Error Codes Order listed:

SafeMode works -- using it now.
Ran SFC /ScanNow (everything OK, no errors)

Per Nirsoft BlueScreen report error caused by ntoskml.exe

Attached is file requested.
(Remove attachment 9/10/2017 since resolved)

Any help appreciated.

Hello dw mate could you follow this please
Now before we can help we do need to know what is in your machine so please do this System Info - See Your System Specs - Windows 7 Help Forums
or either enter the specs of your system in your forum profile the specs will appear when we click on that little box bottom left of the post screen it is for me the preferable option as it is easy. As you may appreciate it is very hard when you donít know what one is working with for example a diesel or petrol engine.
*(pretyped to save time)
Now there is this in the dump files
Something has gone badly wrong with the registry.  If a kernel debugger
is available, get a stack trace. It can also indicate that the registry got
an I/O error while trying to read one of its files, so it can be caused by
hardware problems or filesystem corruption.
It may occur due to a failure in a refresh operation, which is used only
in by the security system, and then only when resource limits are encountered.
Arg1: 00000001, (reserved)
Arg2: 86e17238, (reserved)
Arg3: 00f4f000, depends on where Windows bugchecked, may be pointer to hive
Arg4: 00000374, depends on where Windows bugchecked, may be return code of
	HvCheckHive if the hive is corrupt.
So I would personally start with these
SFC /SCANNOW Command - System File Checker - Windows 7 Help Forums
Disk Check - Windows 7 Help Forums < if necessary include the /f and /r in the command line as per Option2

NB SFC is often best run for three consecutive runs but the choice is yours

On a further note

Please check your ram AND the slots - dead ram stick or slot broken
swap them in/out/about

System info is showing 8GB but LESS than 4 available.

Just realised your running 32bit ONLY configures MAX 4GB

Thanks guys.
Rolled back to previous Restore Point on 9/7/2017 and everything appears to be OK now.
However, would like to know real "cause".
Will try and update system specs.

Yes well I suppose you could plough through the event viewer but it could take a really long tie unless you can pin it down to a date and time.
