you might need to get a new mobo if I am reading that your gfx card has only 3mb or memory.  that tells my that it is most likely very old and maybe integrated in the mobo.  If your mobo is lets say from 2000 back you can only buy pc133 or pc100  type RAM and the largest they sell for that I think is 256 mb.  These RAM sticks that are pc133 and pc 100 are quite expensive.  If you want to get a new processor then it might be hard since it is an old computer and some new processors now will not fit in the old socket that older processors go in.
