I have an Dell laptop ( 4 yrs old). When I boot up, applications are loaded fine(in systray). While this is happening I am able to move the mouse.  At some point the system freezes and I have no control over anything ( mouse, function keys, etc).  It happens towards the end of loading all of the start-up applications. I have started the PC in safe mode, removed and re-installed the mouse driver.  It operates ok in safe.  Rebooting in normal results in same result.  I don't have a diagnostic  disk.  Is there another driver that I should reinstall or other steps to try?
