Ok, I am completely new to this whole overclocking thing, so please bear with me and my inexperience. I saw on a website that you could overclock your graphics card to increase the performance of games. The site suggested that I download a thing called the Coolbits Regristry Tweak, which would unlock something that would allow me to overclock my Nvidia video card. So, I did exactly what it said, downloaded it, unzipped it, applied it, and restarted my computer. But, when I turned it back on and opened up the Nvidia Control Panel, the option hadn't been unlocked. My graphics card is an Nvidia Geforce Go 7600, and I am running Vista. Does anybody know what I am doing wrong? Thank you!
