basically you really need a newer system, imo, it would be better use of the upgrade cash.
However, try going to crucial.com and run their system scan to see exactly what ram you have. IMO, if you are going to increase ram, go to 1 gig. As far as the confusion on the ram, usually the pc manufacturer will use the cheaper ram to keep costs down even though the motherboard will support something better.
as far as your video card, someone else will have to help, but generally you will need a better power supply - especially if gaming.
