Hi:

5 Beeps, flashing red light means there is a memory problem of some kind.

I can't find the troubleshooting guide for your model but here is the general troubleshooting guide for business PC's which all use the same beep codes.

See appendix A, page 56 for the troubleshooting steps for the 5 beeps...

You're very welcome.

While I am not a PC repair tech by trade or training, I would say the motherboard has a problem.
