System won't boot--WinFast NF4UK8AA

Specs: Windows XP
I'm rebuilding a system with a Socket 939 AMD 64 processor (3200, I think). I have the mobo and processor in a new case with only the power switch connected in addition to the power hookups. The system comes on immediately when I turn on the PSU switch, runs for about 5 seconds with a long beep, then shuts off. Could it be that the processor is bad? I blamed the mobo and/or video card when the other system died. Hoping I haven't replaced all the wrong parts.

You should always benchtest the components BEFORE you install them in the case. But since the motherboard is already in the case, you should have only the following connected:

- one stick of RAM
- power supply main ATX plug + 4-pin ATX12V plug
- power switch (no other case wiring)
- video card (or onboard video) w/monitor connected
- keyboard

"Could it be that the processor is bad?"

If you're getting a beep (or beeps), that's an indication that the CPU & board are *probably* good. The beep pattern will give you an idea of what the problem is. I believe your board uses a Phoenix BIOS? Here's the beep code list:

OK. Retried it with this configuration. Still starts up, runs for 5 seconds, then stops. Keyboard lights flash, but I don't ever get any video display. I'm getting only one continuous beep before it shuts down, not a series of 3 or 4.

In reading my manual (duh), it mentions only AMD 64 3500 and above and a couple of FX processors. Could this explain the funky behavior? I'm pretty sure that the chip is an AMD 64 3200. I haven't rebuilt a computer in a while, and only looked at the socket configuration when I bought the motherboard. :(
