Computer beeping and not booting up or sending anything to the monitor

[dewap]

Hello,

Edison came and changed out our meter. I powered down our computer while they did it. Since then we were unable to turn on the computer. We replace the power source but now it just beeps and nothing else. no signal to the monitor... nothing. What could it be?

Full system specs please. Also describe the pattern of beeps the best you can, what you are hearing is a beep code which indicates what type of error was encountered that is keeping the system from booting.
