This is quite strange. Whenever I installed ati tool, and rebooted windows would always freeze on windows loading screen. To fix this i would go uninstall ati tool and restart, this would fix the problem. Yesterday I formated, thinking that maybe my windows is fubar, and I reinstalled windows onto a 2nd hd that i got. After that I booted up, installed drivers and installed ati tool. Rebooted, same problem. Whenver I don't have ati tool the pc works fine, but with it windows fails to load. The things i turn on in ati tool is temp viewer, fan control, and setting the frequincy to 128 from 255. Im actually thinking that setting frequincy is causing the problems, but im open to any other suggestions. Thanks!
