Hey all, Earlier today, using RivaTuner 1.06 and the 169.21 Forceware Drivers, I tried the "Enable Driver-Level overclock", and selected to reboot. The machine would basically then boot, but as soon, I'm assuming, it tried to enable that, it would lock up. Ok, kick me, understood. I do remember when I installed the 1.06 it said the 169.21 Forceware drivers hadn't been tested on that. Bad me, I pushed on. Anyways, I just booted to safe mode, uninstalled the Nvidia drivers, and reinstalled 169.21 and 1.08 now. All is fine. My question is this. I'm assuming RivaTuner kicked some flags in the registry that would try to enable software level over clocking. Anyone know what those flags are? I was just wondering, because doing a quick edit of the registry to turn it off, would be easier than uninstalling/installing the drivers again.
