I bought 4 gigs of ram, and this motherboard only supports 2 gigs 1 gig for each card.
SO instead of returning the ram ill just upgrade the motherboard, have any recommendations for me?
thanks if so, another question, can you just put any motherboard in, of course that will work with whats already inside the PC?

Any motherboard is better than an eMachines motherboard.
You are strongly advised to replace the power supply as well while you're upgrading as the existing one will cook any board you plug it into.
The only thing is you would need to do a Windows Repair and I dare say you don't have an XP CD?
