If you have 2 4600's, can't you try the processor from the bad machine in the good one to eliminate that possibilty?
I just looked into a new mobo for my 4600 and Dell said it was $140 and out of stock. From what I heard Dell has made about 3 different MBs for the 4600, so the price might vary.
I decided that before I buy a mobo from dell, I would buy a new case/psu and something like a ASUS mobo and xferr the rest of the hardware from the dell to the new unit. The cost would probably be about the same and in the end you would end up with a superior machine to the 4600.
I got lucky though the new PSU fixed my problem.
Check this out, found it on another thread:
Yes, I've considered switching the CPUs to try to isolate if it's the motherboard or the CPU.
I've never taken a P4 out before and was nervous that I'd damage something. Most instructions I see have folks doing it without the heatsink installed. Can I do it without having to remove the heatsinks or is removing and reapplying the heatsink no big deal?
Are there instructions specific to this type of socket/motherboard?
Finally, if I do get a different brand of ATX/P4 motherboard, would have to re-format/reload Windows and everything on my hard disk for the new motherboard/bios?

Thanks for the tips. I swapped the CPU and RAM with the good 4600 and they worked, so now I'm basically down to the motherboard. Looks like that's the bad component... so off to finding a good price on motherboard replacement.
