Alienware 18 laptop, just over 3 years old.
Original Setup, WD hard drive with 80gb msata
started having problems with it when it was upgraded from Win 8.1 to 10
Tried going back to Win 8.1, but system froze on any reboot.
Did a full restore, from factory restore partition, same result. System would run fine until a reboot or shut down and the hang upon startup.
If I took the hard drive out and booted to it in another system then put it back in the laptop and booted it would run until reboot or shutdown.
Ran Western Digital Diags came back error free.
Ran MemTest something like 16 or 18 passes, no errors.
Tried another hard drive, same result.
Loaded Windows 8.1 from original disk, formated all drives removing all recovery partitions and everything.
Loaded up and tried installing drivers. On second driver system froze.
As things progressed, tried reloading windows 3 or 4 times, but as soon as I started to load the first driver, no matter what I chose, the system froze.
I then loaded windows and proceeded directly to Dell support site to begin downloading drivers direct. Before the first one ever got downloaded the system froze again. Windows is not corrupt again and won't restart.
I also ran the Dell diagnostics, including the full memory scan, and everything passed.
