I'm pretty sure hypermemory isn't going to let you run a game that requires 512 mb or 1 gig or whatever you can't run with your graphic's card. And I'm pretty sure you can't just say "it's not working", it's something that the card automatically does if it has to
At least that's how I understand it.
Either way, get a new graphics card.
Actually it's a laptop from craigslist, it had multiple problems, and it got switched from windows 7 to vista multiple times. So i'm probably just gonna throw it away and get a new one.
