Start your computer in safe mode Safe mode starts Windows with a
limited set of files and drivers. Startup programs don't run in
safe mode, and only the basic drivers needed to start Windows
are installed. For more information, see What is safe mode? Safe
mode is useful for troubleshooting problems with programs and
drivers that might not start correctly or that might prevent
Windows from starting correctly. If a problem doesn't reappear
when you start in safe mode, you can eliminate the default
settings and basic device drivers as possible causes. If a
recently installed program, device, or driver prevents Windows
from running correctly, you can start your computer in safe mode
and then remove the program that's causing the problem. For more
information about troubleshooting problems in safe mode, see
Diagnostic tools to use in safe mode. Remove all floppy disks,
CDs, and DVDs from your computer, and then restart your
computer. Click the Start , click the arrow next to the Shut
Down , and then click Restart
