How can I expand my computer's ram and better it's video card?

I have an Intel 82810E Graphics card with512 Ram, but I can't run my favorite games like halo, just because i either don't have a better graphics card or i don't have 32 bit video. Also, my ram could use an improvement. My main question is, how can I resolve all this without spending more than $10?|||you can't. You have to go buy a better video card and upgrade your ram. price would be in the hundreds, not $10
