Do i have PCI or AGP?? I want to play SPORE on a four year old computer?

I have a four year old Hewlett packard and Its processer is AMD athlon 3000+ and Um.. The graphics card is a VIA/S3G UniChrome IGP and I opened my computer thing and it showed 1 brown thing and 3 white things below it. I think that is the graphics card or something?? I want to play spore but it said my graphics card is under their minimum specs.
