Remove the password? Well, I suppose that is possible, but not likely. What happens if you start the computer and hit the ESC key instead of putting in a password?
More likely, you want to go to safe mode.
Go to start>run, and type MSCONFIG, click OK.
Go to the startup tab, uncheck all items but systray. Click OK and reboot, now how does it run?
