Well, I dont have the catalyst control center installed at all. I may be just overly jumpy but I went through about 5 months of shear terror, 10 system total crashes (my software includes Adobe Master Suite, MS VS 2010 Ult and many more, a rebuild is about 22 hours), and countless debugging hours. I was finally able to convenience the good people at Gigabyte to send me two Nvidia cards to try and see what would happen. I took out ATI drivers, put in Nvidia cards, installed drivers and have not looked back.
Would you mind to provide a link to the chipset drivers you are using? I hit custom on the ones I got and it doesn't give any tic boxes for what it installs only lets you choose where.
