Windows 7: BSOD starting Windows 7, error 0x0000007F

BSOD starting Windows 7, error 0x0000007F



After recent Windows 7 updates my Lenovo X201 laptop restarts when starting windows. BSOD appears.

Error description:
STOP: 0x0000007F
Ntfs.sys ....

Safe mode with networking is ok.

Already tried to do some things:
- system restore - error occurs when restoring
- chkdsk - finds no problem
- memory test - finds no problem
- SATA mode changed from AHCI to copmpatibility - BSOD even faster than before
- unistalled recent Windows updates - the BSOD is still there

SF tool zip attached. Logs created in safe mode since the normal mode don't work.

Please help.


Thank you Arc.

The problem is the conflict caused by:
- CMGShCEF.sys (CMG Shield for Windows Driver is a driver file from company Credant Technologies, Inc. belonging to product Mobile Guardian Shield)
- DisplayLink drivers for NBdock1920 USB dock station.

I've uninstalled DisplayLink drivers in safe mode (Windows Installer needs to be enabled in safe mode to do it). Email to Credant support has been sent also if they can update the CMG driver.

Probably caused by : CMGShCEF.sys ( CMGShCEF+f27c )

Update it using Data Protection Solutions | Credant .
