What Graphics Card Do I Need For My Computer?

I have a Packard Bell iMedia 1309 - I have looked everywhere and a noob with computers. All i know is i have a 'Bali (GA-K8VM800MNF) �ATX Motherboard Ver 1.01' motherboard and 184pin DDR400 RAM and 1.5gb atm. I am upgrading my computer in time, and windows rates my graphics card at an appauling 1.0. This is sad so i need an upgrade. I don't need an amazing one, price range under �40. Any ideas or websites? Thanks guys :D
