I am taking it that since you have not responded to oldturkey03 about post errors that you are not getting any. You also state that the system runs great, when running. I am guessing then that the system just hangs while loading the operating system. I would try reinstalling your operating system and drivers since this does not sound like a hardware failure.
Since you reinstalled Vista, I lean towards when the BIOS is reset from the jumper that it goes into a fail safe mode with no hardware detection, so you can boot and get into the BIOS. When the computer is shut down it relearns itself. My first thoughts are faulty memory or faulty memory slot. Possibly a bad HD controller or cable. I've seen several computers with bad sata cables make it part way through loading the operating system then hang.
