So I was building my PC and every thing was going fine until I booted the computer up with a hard drive that had windows already installed on it which was windows xp. The hole thing kept showing a blue screen then it kept reloading the windows loading screen, so I turned it off and now the only way for me to get a a display on I have to take out the graphics card and put the vga cable through the motherboard for me to get display. So I'm getting really scared that my graphics card is broken, the fans do spin on it. Do I need to get a new hard drive and put new windows on it then update the driver will it wok then, plz help I don't want to waste $200.
