This post is for the benifit of anouther user: "Cheerup347". Though, I have directed her to use this post for a source of information. Prior to cheerup347 putting in her own information, I know that cheerup347's computer uses pc 4200 ddr2 ram (533mhz) and a 2.8 ghz dual core processor, the manual says FOXCONN 945GZ7MC - 945PL7MC - 945G7mC - 945P7MC. So, I think thats the motherboard name, but these are hard to find. Unless anyone out there can find one of them.
