1. Microwave noise 2. keyboard and beeping

Make sure oven is plugged into a grounded outlet, and that the outlet is actually grounded.
Although extremely rare, I have seen ovens where insects were walking on the back side of a control panel, and causing problems. Could also just be some sort of electronic failure.

Hp pavilion a1220n comptur will not start unplugged unit and when i plugged to back in it would not start

Do you see anything on the monitor screen? Does the tower make any beeping noise or clicking noise, or does the fan tries to start up when you power the computer on? Are the cables connected properly?
If you see anything on the monitor screen, or if you hear a beeping sound, let us know so we can diagnose further.
