Windows 7: BSOD Stop c000021a - only boots in disable driver sign. enforcement

BSOD Stop c000021a - only boots in disable driver sign. enforcement

Hello Everyone,

I am looking for a solution to a problem which started to occur today.

Last night I was prompted by Windows to do some updates, after they had finished my computer shut down normally. When I booted my computer today I was greeted by the BSOD with the following error code:

Stop: c000021a. The initial session process ... terminated unexpectedly with a status of 0x00000000 (0xc0000428 0x000106a0).

Windows is unable to repair the problem, I can't boot in safe mode (with or without network, cmd or otherwise) and Windows can't find any recovery points to recover the system to, nor can I boot the computer from the last known working configuration. After some frustration I tried every option from the advanced boot menu, and lo and behold, the computer booted when I booted in disabled driver signature enforcement mode.

The computer seems to work fine in this mode. I ran sigverif.exe and it found one driver that was not signed, a driver used by Daemon tools lite (can't remember the name). The driver was signed, but still my computer wouldn't boot normally, so I tried to remove Daemon tools (hence why I can't remember the name), but the computer still won't boot normally.

Windows keeps telling me that I have three important updates to update, but I can't seem to update them. The updates are KB3067903 and KB3065987, but I have no idea if they are connected to the issue.

I am attaching a screenshot from dxdiag and from the DM log collector, if you need anything else to help me solve my issue, please don't hesitate to ask. Everything that could be helpful would be greatly appriciated!

Thanks in advance,
