Many thanks Fassou, I'll try it,
The strangest thing is that when Catalyst is open it doesn't crash, that's why I hadn't tried what you said before, haha.
It seems like the antivirus is messing something up, and when you open Catalyst it loads into memory and fixes it.
If I don't install antivirus it doesn't crash, and of course there's no need to open Catalyst.
Another thing is that if I set Windows to 23.97hz, that is, if the program doesn't have to make the change, it doesn't crash either.
Crazy as hell, let's go
Regards and thanks again, if anyone comes up with the idea of hiding the catalyst...
