Are you sure that it is in Safe Mode?  It *may* just be the wrong screen
resolution which looks like Safe Mode.

Does it say 'Safe Mode' in each corner of the display?

If you are sure that it really is in Safe Mode, what happens when you
shut-down and re-boot?

Does it automatically run Scandisk?
Does it then attempt to start in Normal Mode?

Norton!!! - perhaps? - "Computer Starts Only in Safe Mode and System Restore
Does Not Work Properly"

    - Or, just maybe :-

Have you got the 'Enable Startup Menu' box set in msconfig?  Run
msconfig.exe and on the General tab, select Advanced and uncheck the 'Enable
Startup Menu' box.
