I would appreciate some help in troubleshooting the following problem:

This is what I need to do to start-up my computer.

1. Upon initial boot-up, my video monitor indicates no signal and I hear a single, repeating beep coming from the computer. In addition, there does not appear to be any power going to my mouse.

2. I then power-off the computer via the main power switch and reboot...after this stage, power goes to the mouse, but the video monitor still indicates no signal. Also, I do not hear the single, repeating beep coming from the computer.

3. Finally, I will power-off again and reboot and everything will function accordingly.

This problem began to occur when I replaced the power supply. However, I can't seem to figure out why.

are you sure you hooked up the power supply correctly? are you sure you got the right kind of power supply? is it properly sized for the computer (as in you're not trying to use a 200 watt psu on a machine that needs a 400 watt psu)?

as for the beep? is it really one beep at a given interval (like beep (pause) beep (pause) beep) or is it a pattern of multiple beeps?

I swapped out the old power supply with a new power supply of the same brand and voltage.

I swapped out the old PS with the new PS, cable by cable.

The beeping is one beep at a given interval such as the following:

beep (pause) beep (pause) beep (pause),etc.

I appreciate the help.
