I had my Asus Desktop (that I built) in storage for 3 months because of my house fire. I plugged it in yesterday (not sure I have the right cord) and all it does is beep. The blue light seems to be on the front side of the tower but not sure what the beeping means. I have my monitor connected but the hard drives don't seem to be recognized. I'm hoping I just have the wrong cord attached.

Should I have a cord with a power box attached or just a 3 pronged plug into an outlet.

Servicemaster said all my electronics checked out and should have been working. They delivered them on Friday in a jumbled mess of cords.

I have an Asus M2-NE motherboard.
