Local Security Authentication Server (Lsass.exe) has denied access to a
process. Check the events view under Security and under Applications. Start

Run > type "eventvwr" (no quotes). When event viewer opens select that

afore mentioned sections and check for warnings and errors logged.
Double-click an event (right pane) to view details. A suspect service or
application can be started and stopped to see if you can reproduce the
error.

Can you boot in Safe Mode?

Restart the computer, press F8 until the text Startup Menu is displayed.
Select "Safe Mode". Once booted scan for malware and viruses. Below are a
few good ones I have had success with, and I use more than one when trying
to fix problems.
