Okay thanks. I've installed the new driver
but it said warnings occurred. I get this a lot. I got it with beta 4 too, even after uninstalling and using driver sweeper.
I've attached the reports, but nothing seems to show in the actual 'errors' section.
EDIT: Oh I've had this issue before. sometimes when I install the drivers
it does not ask to restart afterwards, and on restart, catalyst won't open.
