A while ago I decided to update mu GPU Drivers (BAD decision!), and after a few tries, someon suggested me to first uninstall the drivers, run Driver Sweeper and then install the new drivers... I did that, but when I went to install the new drivers, the CCC and the drivers would not install! It simply ran the installation, did not give me any errors, but it didn't install either the CCC or the drivers! So then I tryed many ways to install the drivers (because now is with some crappy Standard VGA Adapter) but it simply will not install it!
So, I went and formatted my pc (with the Windows 7 SP1) and still got the same issue!
My pc is a MSI GX660 notebook, and the gpu is a Radeon Mobility HD 5870
Ouch. Did you download the drivers from MSI or from AMD?
Most video drivers for notebooks should be downloaded from the notebook manufacturer's web site and not AMD or Nvidia due to proprietary tweaks to original graphics card specifications, compatibility issues with other components, or some other reason.
