Hello, I recently had to reinstall windows vista, so after the process was done and the welcome screen comes up. It shows my computers specs and I see that my graphics card isn't up there. When I was trying to fix my computer I took out the graphics card and put it back in, note: I did this before I put in the operating system disk. Now I can't play any games, and my computer is soo slow. If anyone has any suggestions please tell. Thank you.
