cpu

I just built a new computer and when I first powered it on I got a continuous beeping which according to the manual means a power failure. After moving the voltage switch to the left a little I was able to get the beeping to stop. Even after the stopping though the CPU fan doesn't spin, and there is no display on the monitor. All the other fans and lights come on in the computer though, the DVD drive is working and ejects the tray, and the hard drive sounds like it spins up.

Has anyone seen this before and know what is wrong or what has failed?

OK, so I'm guessing that it's dead. It's not my machine, and the owner is on a very fixed (IE, none) income. I'm generous, but I'm not that generous, since I already gave him what (at the time) was a fully functional and fairly well-equipped machine.
