Replacement Motherboard

I don't think anyone carries 939's commercially anymore; if that's the route you want to take, your probably going to have to take your chances on ebay. If you don't mind upgrading, you could probably get away with just buying a new mobo, cpu, and ram (ddr doesn't work on ddr2 boards).

This mobo/cpu combo is $120 (athlon II X2 240-2.8GHz + GIGABYTE GA-MA785GM-US2H)

This ram is $36 (2 GB-minimum)

This ram is $65 (4 GB-Optimal)

Ascendtech.us and 3b tech both carry a few socket 939 boards. These boards aren't fancy, but will save you over paying someone top dollar on ebay for a high end board. Not many left, and most are used or refurbished.

Hi Pepperman / o1die

Many thanks for your advice. I didn't think it would be easy - I will see if Ascendtech or 3b can assist. Otherwise it is time to pawn a kidney and upgrade....

Thanks again....
