Does my graphic card need renewing ?

I would try uninstalling it, make sure all registry keys are deleted,
and reinstall, as for you graph card slot agp,,most anything needs pci-e,,you should look at a system or motherboard with pci-e.
With amd and intel fighting, a good new one that is 5 times faster
is very cheep. Cyberpower has a desktop cpu-amd x2,,5000 with pci-e and ati 2100 graph card with vista for around 428.00
This is a fast pc,, If you want core 2 duo it is over 500.00
You can look at dell,,,I just hate there motherboards.
I only run ASUS boards.
