Older PC not registering the Graphics Card?

Hey everyone,
So I recently booted up an old tower of mine (HP Pavilion 7955) for my dad who wanted to play some older games of his that won't run on current systems. Anyway, he did a system restore on the thing because it had so much junk on it. Big mistake- now the computer won't run any of his games period. I opened up "dxdiag" and also installed something called "Speccy" onto the machine to take a look at what kind of graphics card we had (He replaced the old one that came installed into the machine with a newer one) and nothing would pop up. The computer refuses to acknowledge the graphics card in it and this graphics card has been installed into the computer for years and we have never had a problem with it until now.
However, I managed to figure out that it was a ATI Radeon 9000 64M graphics card by opening the PC up and looking at the sticker on it.
Now that I knew what the graphics card was, I went and downloaded a driver installation into the PC.

But here is where my problem lies: The drivers won't install as the computer claims that the drivers are not compatible with the hardware. But I feel that because DXdiag and Speccy couldn't tell what the graphics card was, the computer itself doesn't know what graphics card it is running on. Stupid because I am having no visual problems with the PC and it runs like it should only it doesn't register the graphics card when I open up the previously mentioned programs.
Anyway, as I said- it is a ATI Radeon 9000 64M (or 64MB?) graphics card running on a Windows XP 32-bit computer. That graphics card has been installed onto the PC for YEARS and we haven't had a problem at all until my dad did the system restore on the computer. I am thinking that because the computer itself doesn't know it's own graphics card- the drivers won't install.

Anyway, could really use some suggestions on how to fix this because I am out of ideas.
