Computer broke while using ComboFix.

Ok so I was directed by a user from Safer-Networking forums to use ComboFix and sometime late in the second attempt to use it (at the point where it says to wait for a restart) it stopped running and my computer hung. I tried waiting for a few hours but nothing changed. So I manually restarted my computer. Ever since then I've been getting a BSOD on startup:

STOP: c000021a {Fatal System Error}
The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000135 (0x00000000 0x00000000).
The system has been shut down.

I poked around a bit and discovered that this is the same BSOD used by MalwareBytes' Anti-Malware to force a restart. Based on the evidence, I believe there is some flag that was set by ComboFix to cause the BSOD (and thus a restart) that was never removed. Could somebody who knows a bit about ComboFix help me out? Here is a link to the thread I was involved in when using ComboFix:

We tried a few things but ultimately none of them worked. Could somebody please help me?

Combofix is not to be used outside our HJT forums
I would suggest posting in our HJT forum or going back to where you were being helped. You never did respond back and they closed your thread.

FWIW, I agree with Shaba. It's time to reformat and reinstall

i second that thought
