I have done a simple remove/install of one driver but thatwas my first and I'm still a bit stupid about these things. Since I have a GTX285 and experience the freezing problems, I'd like to do a good job of removing before installing a driver and pray that it helps. Simple instructions leave me wondering, I need a step by step: example: 1 download new driver and save to a folder 2 shut down computer 3 start PC in safe mode 4 remove old driver 5 run driver cleaner software 6 install new driver 7 restart PC. Can you remove, then install, then clean? How much work has to be done while in safe mode, when? etc.... Thanks!
