ATI HD 3650 software install. issue

Ok so i bought this graphics card http://www.powercolor.com/Global/p [...] uctID=1747 because my ATI Radeon 9600xt 256mb died on me and i got this ATI3650 one and i have a few questions.

1. Firstly, i inserted the card and the monitor turned on (which it stopped doing with the 9600xt), uninstalled old drivers etc, inserted disc for the new card and i get this message:

What do i do here? I click ignore/close, nothing happens.

2. I tried installing the latest catalyst drivers but part way through the installation i got a 'Severe' message saying 'Setup did not find a driver compatible with yoru current hardware or operating system. Setup will now exit'...
These drivers, http://game.amd.com/us-en/drivers_ [...] radeonx-xp , are they not the one?

I've uinstalled my previous drivers and the computer just works on the new video card in some low resolution, quality mode...yet when i turn on the computer i always get some message about some drivers not being found or something.

Btw i have an AMD 64bit 3000+ processor, and the computer runs on XP pro.

Please, i need dire help, because everyone in my family is having to use the laptop (it is mine, but theirs too) Thank you.
