Problem with ATI Drivers on a 9600 Pro

I am running a Dell 400SC with the Intel 3.2ghz chip. I installed an ATI Radeon 9600 pro some time ago but have been having a consistent problem trying to use the updated drivers from ATI. The last one That I found that I could use is version 3.7. Whenever I try to update and go to a new driver I get a blank screen when trying to install and then have a devil of a time getting back to 3.7 which does work. Monitor is a Dell 18" ultrasharp (running DVI). I would really like to use the newer drivers for better performance but am gunshy trying them with all of the problems. Any [email protected]
