It's processor does most of it's work, and it has -not terrible- integrated graphics, but it originally had 2gb, windows vista (ew) and the ability to run Skyrim at a choppy but playable framerate. Then my hard drive died, and my friend's RAM fried, so I loaned him my RAM. I got the 512MB's from my old (I mean old, like circa 2003 or 2004) laptop. Once I got the new hard drive I just stuck with XP, because I wanted Windows 7 back, but my install disk is 64-bit only, and 64-bit Windows 7 requires 2GB of RAM.
But I digress. I tend to ramble, so feel free to stop me at any point :P
