I think our man here got raped by his computer vendor. I'm 95% sure that they only gave him an intergrated onboard video chip, which explains the low amount of memory. And to make it worse I think its a Trident chip, which has almost to none 3D rendering power on it. However, from what I know of intergrated Video cards, you can swap "system memory" to "video memory." So you should play around with your system settings a bit and see if you can do that, or even go into the bios and see if there are any settings related to this. But man, if I were you, the first thing I would do is call up HP and make the mofo people who sold you the system give you your Geforce4.
