Sorry for my English
I have Windows intalado pro 8.1 x64 (clean install)
When I watch a video (youtube) pixsela the screen (not always) and recovered (serious driver error).
The Windows version is installed brings 13,150.
I downloaded 13.9 and 13.11beta versions. But the install does not update the version of Windows, follow with 13,150 when it should show 13,152.
At the beginning of the installation indicates that it will create the folder C: \ Program Files \ ATI Technologies, but this folder is empty.
I installed with administrator privileges and still the same.
Is there any way to fix it.
