WMRUNDLL.EXE - Application Error

The Instruction at ”xxxxxxxxxx” referenced memory at “xxxxxxxxxx”. The
memory could not be “read”.

Click on OK to terminate the program
Click on CANCEL to debug the program

I get this error when the login screen comes up. No matter what i do
click ok or cancel the machine will restart.

I have tried
imaging it with a new image
new memory
deleted all the entries out of HKLM\Software\novell\Workstation

Thanks in advance,
