Going to factory restore the PC I bought from my friend a few months back since it's full of shit I don't want and it'll take too much time to delete one by one, and the PC has an ATI Radeon HD 6670. My problem is, would I have to install the graphics card once it's rebooted? How do I install it? I do not have the CD for it nor does my friend...or does the CD ONLY have the driver needed? If the PC would work the same even if rebooted then I'm okay but I'm just trying to make sure here.
