How can I install ati drivers without paying for software that detects what card i have, I know its ATI Radeon but that it!

If you don't know what model card you have you can take our hardware scan which should tell you which one you have. Then you should be able to find it on the manufacturer's website. ATI designs the chip but someone else makes the card. If you find out & post the make/model I can try to help you.
