Sorry, your card is f*cked! Time to get a new one! It's out-dated now anyway. The Geforce2 MX's are going to be less than £100 after Xmas so you'd be better off just waiting until the new year and buying one of them. It's a really good investment. If you've got money to burn, you could buy a Geforce2:GTS like me because they are only about £180 - £200 now.
