ok when i go into my bios to overclock my athlon x2 5600+ from 200x14 to 208x14 or higher, when i reboot 2 things happen. #1 if i rightclick on my desktop the nvidia control panel option disappears. #2 if i open the control panel from the start menu, my sli options disappear. but when i go back to stock settings both options come back. has this happened to anyone? running 8800gt sli'd on gigabyte m55sli-s4 with 700w psu 2 gigs g.skill 6400
