lsass.exe "object name not found"

[mrlucio]

Everytime I try booting up my pc I get this error message:

lsass.exe "object name not found"

All I can click is "ok" and then it reboots. Then it cycles through again.

I cannot get into safe mode either. This sucks, because i have a report to write. :0(. Can somebody help me?

P.S. I even tried doing the "in place upgrade" and i still get the same error message.
