Was doing a virus removal on a clients computer and after restarting out of safe mode (Where I ran AVG, Spybot, MBam, and Hitman Pro) the computer began to bsod. The stop error is c0000135 and renders me unable to access the computer even in safe mode. After much research I have run across various "fixes" such as editing registry keys HKEY_LOCAL_MACHINE\FIX\CurrentControlSet\Control\Session Manager\SubSystems which suggests to change a registry entry from pointing to consrv.dll and make it point at winsrv.dll. This seemed to work for many people but unfortunately the clients registry was already pointing to winsrv.dll. I also followed the route suggesting AVG Rescue tool but the problem persists.

EDIT:Was browsing through system32 and as it turns out consrv.dll was missing completely, replaced file with a winsrv.dll renamed (saw it suggested on a forum somewhere) and pc now boots briefly before bsod'ing to a c000021a

In addition to the log please tell me if the winsrv.dll is still in system32? It should be, but I want to make sure.
