First of all, sorry for my English.....I've got an annoying problem that is driving me crazy. Because the dedicated graphic card is much better than the integrated, I use Switchable Graphics Technology....but for some time a I've got a problem. I can't open Catalyst Control Center .....sometimes I've got the problem with mom.implementation. I tried to install the latest drivers for the graphics card and the latest net framework but no success. PLEASE found a solve....I can't play any game because all of them are lagging.
