BSOD with error code "Stop: C0000221 Unknown Hard Error"
Enountered a BSOD that said something along the lines of "Unknown Hard Error" with the code in the title followed by the path: \systemroot\system32\ntdll.dll
It then said something about dumping physical memory to disk. I encountered this BSOD after I purposely powered down my machine and it had been turned off for a couple of hours.
All help is greatly appreciated.
p.s. I encountered an unhandled exception error when trying to run the SF diagnostic tool so I hope it completed sufficiently.
Thanks!
