with the system specs in my sig, I tried to up the fsb by 20 using the nvidia system utility. As soon as I did that, my mouse icon just went crazy on me and disappeared. I tried restarting like a million times, system restore, using a different mouse, shutting down, praying, loading fail-safe on my bios, and using windows safe mode. NOTHING WORKS!!!!!!!!! if any of you might know a solution please help!!!!!!!!!1
