Thanks for your patience. Incidentally, I found the best route to Safe Mode in W8 is to click on restart while holding the shift button down and going via 'Troubleshoot'.
Unfortunately, I still could not uninstall older drivers. Initially, the uninstall works properly and 3062's impending departure brings up the box to tick for deleting associated driver files. After that, though, clicking on 'uninstall' does not bring up the box and I just cannot get rid of the driver files for 2768 which means they are recovered on restart as far as I can tell. Either I am still doing something wrong or there is a glitch with my set-up. Is there another way of deleting those driver files?
Sorry to be a pain.
