Yeah, you're right. That is the problem. My windows 7 graphics card is crappy. Any ideas on how to get a new one?
You don't have a windows 7 graphics card.
You have the same graphics card as you did before, unless you got a new computer, or opened it up and put a new one in.
If you just bought windows 7 and put it on your old computer, you don't have a driver at all.
If anyone in your family knows anything about computer hardware you should ask them first. They would be able to work more efficiently.
