This is the main problem. Upon doing everything by the book, I get as far as "installing" the new card only for it to get to the end of installation and to be told it didn't install as the parameter is incorrect.
Now after over 6 hours yesterday of looking into my computer and trying to sort it, I have found something that may be the problem. My ATI drivers cannot be manually uninstalled through add/remove programmes. It just won't let me and rolls back at the end of trying to uninstall it every time. So I tracked down every ATI file and uninstalled manually. Every file that is beside the ones that will not remove. Its in Mycomputer/c:/Windows/System32/Drivers - and a load of ATI files. When I try deleting them they just reappear straight away!! I think this may be the problem.
How do I get rid of these files permentally, or if you don't think that is the issue then what should I do?
Thanks in advance, I'm at my witts end with this!
