longer verison: my laptop came with a manufacturer-customized graphics driver, i wanted teh newer one from Gigabyte directly... every installer i try says it's incompatible with my Windows. is teh laptop maker locking this down, or is my Windows install broken? i would realy prefer not to reinstall Windows just to update one driver... if there is a way to check what the installer is actually comparing, i would love to know it. any ideas??
