Someone Please help me with DXDIAG info & tell me what driver i need

Ok, My computer got a virus and completely died on me. I couldnt get to windows/safe mode-- Nothing. So a friend of a friends got it up and running for me and installed Windows Xp Professional on it (I had normal WIndows Xp before) So When I got the computer back it booted up to Windows XP Pro and worked just fine, all i needed to do was tu run Windows Update, so I did that. So i tried to install some video games (Halo: COmbat EVolved and Knight Online) both games worked just great before my computer crashed, but now when I try to run them they both have problems with DirectX. Halos error message said something about not being able to run directdraw and to use DXDIAG (which i did) and knight online told me that it "Cannot Create D3dDevice". So long story short nothing seems to work and i dont know **** about computers. I dont know anything about drivers or video cards or anything, but it says "the system is using the generic video driver. Please install video driver provided by the hardware manufacturer" i dont know what the hell im doing, all i wanna do is play my old favorite games. I ran DXDIAG and this is what it said:

did you ever add a Video card? if not you have Intel integrated graphics ..
if you want to play some games I recommend you upgrade you memory to 1Gb and a video card. tho it looks you have to go PCI route.

I'm not 100% sure, but I think this may be the driver you need should be here - http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=228&lc=en&cc=us&dlc=en&tool=softwareCategory&query=PC182A-ABA%20SR1103WM%20NA430&product=424182
