2. Is the network cord ( yellow) connected to the computer and the phone jack ?

3. Program not responding ?  CTRL+ALT+DEL

4. Program still not responding?  Shutdown, not restart. Be patient.

5. Ask the kids. They probably know the answer.    

6. Where are you booting from? If a CD is in the drive, strange messages appear.
