BSOD before enter Windows (when Driver Verifier is on)

Hello,

BSOD happened randomly and frequently in recent days. I tried to narrow down the problem by myself but I can't recall what major changes I did to my PC to cause BSOD during the time. Therefore, I took advice from good people here to use Driver Verifier. Then BSOD happened even before I can enter windows...

Here is the system info and dump files after Driver Verifier. Thank you for your help:)

Best,
Allen

Uninstall Daemon tools. It is the most frequent BSOD causer in windows 7.

Let us know the results.

Sorry for duplicated posts. System hang at the moment I submit my reply...

If there are no more BSOD's you may disable verifier now.

You are welcome :)
