SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
This is a very common bugcheck.  Usually the exception address pinpoints
the driver/function that caused the problem.  Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003.  This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG.  This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG.  This will let us see why this breakpoint is
happening.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff88001073768, The address that the exception occurred at
Arg3: fffff88003be5868, Exception Record Address
Arg4: fffff88003be50c0, Context Record Address

Thanks for letting us know!

Hope the good luck continues :)

That's the first time I have seen a Device manager without IDE ATA/ATAPI Controllers How about expanding Storage controllers and post a screenshot.
