Can you reboot into Safe Mode and check the Event Viewer to see if there any
error messages logged that might help in diagnosing the problem? Have you
recently installed any applications or devices that might have triggered
this? Can you do a System Restore to an earlier point in time before you
started experiencing this problem?
