When I re-install windows for a client, I always get all the latest drivers for the hardware, such as Video, Motherboard, network card, modem, (if used), etc, etc.
If your windows is still accessible, you should be able to id the hardware from 'Device Manager', which can be reached from
'Controll Panel' - 'System'.
Also since you're re-installing, then you boot the installation disk, make sure you wipe the 'c' drive partition and replace it with a new one. That will eliminate any 'leftover' problems, with your new installation.
