Good afternoon. I have a Packard Bell EasyNote LS11HR with a discrete AMD Radeon HD 7670M graphics card. After the HDD is broken, I purchased the SSD. And installed in it the official Windows7 64x. Before the installation of drivers with the official registration system was launched in 15 seconds. After installing the driver, the system started running for 1.5 minutes. After I disabled the startup of the Catalyst Control Center, and the system started to run faster. The newest version of the driver also slows down the system startup. Why does the Catalyst Control Center and the newest drivers slow down my system startup? How to fix this problem? Sorry for bad English.
