How to revert catalyst overdrive settings?

[jongko]

I ran catalyst overdrive and when it was finished, The screen was normal for a while. But a few seconds later it turn black and stayed like that so i restarted my desktop. Everything ran fine until i logged in and a few seconds later it goes black again. i cant get back to catalyst to change the settings from there. i can still run it on safe mode but im not sure what to do from there since it says the driver isnt installed...
