I just downloaded NVHardPage SE Build 5 from Guru3d website and clicked coolbit in the options. Found out it doesn't work. Then I unclicked coolbits and my control panel crashes everytime on load. I tried uninstalling and reinstalling the nvidia drivers and still the same thing! The control panel crashes! Please help! edit: btw, I have the 8800gts w/ the 158.22 Forceware drivers.
158.22 driver has no longer OC panel, you must download nTune utility from nvidia website for overclocking. If you have trouble after enabling Coolbits in nvhardpage, try find in registry editor (regedit.exe) key CoolBits and delete it.
