Alrighty, I have had this problem for some time now. I recently reformatted my computer and reinstalled Windows in the hopes that the issue would be solved. But it still prevails. This is what happens. When I first install ATI Tool it runs fine. Then I set it to boot on startup and then close itself. I have tried both methods, registry and Startup folder, but both give the me the same results. They both crash on startup. And also once I reboot my computer I cannot run ATI Tool until I reinstall it. Becuase after I reboot after the initial installation it always crashes and I have to resinstall. In the log it states that it starts and then it is terminated. All I really want to do is to set my video card to my OC settings on startup. I also try SYStool but I got the exact same results. Any suggestion or insight would be greatly appreciated.
