|too my knowledge, catalyst converter for win 7, is only for high spec cards, i use an old x700, and win7 does everything i need to do except theater mode. just wonder why you would need it?|
the blocked accounts can be unblocked simply by changing the user rights., i noticed some on my computer, thought it may have been due to doing an upgrade..however giving my account rights worked fine.
the desktop problems, i suggest a system restore to the earliest restore point, or drop in the win 7 dvd and run a repair of the installation,
sounds like you may have messed up some files with installing catalyst and ati drivers..
i hate computers!
but cant help myself....
