You could try another driver that may work if you want. You just need to know if you're using the 32-bit or 64-bit version of Vista. (If you're not sure, open the start menu,
right click on Computer and choose Properties. It will display it on the next screen.)
Driver for XP & Vista 32-bit
Driver for XP x64 & Vista 64-bit
Just note that messing with drivers can cause nasty side effects if something goes wrong, even though these drivers are listed as compatible with the d630 model right on the driver page. Your call.
