Hi Gino Titov,
Can you confirm that you have followed the installation instructions to the letter?
You must connect the Power Media Dock (docking station) to your notebook when installing the 64-bit driver “ AMD Radeon HD6650M & Intel Mobile HD graphics ”. This driver won’t install if the Power Media Dock is not connected. Note that the driver “AMD Radeon HD6650M & Intel Mobile HD graphics” is a hybrid graphics driver for both the AMD and Intel graphics adapters. If you have purchased a VAIO VPCZ21/Z23 notebook series without the Power Media Dock, please install the standalone 64-bit driver Intel Mobile HD graphics . You must install ALL drivers and utilities labelled 64-bit or 32/64-bit that are available in the Preinstalled download section of your model. Failure to install ALL drivers and utilities may cause some features (for e.g.: Fn-hotkeys, etc.) not to operate properly.

If so can you confirm that you are using the pre-installed OS on your VPCZ23V9R/X and, if relevant, the reason for the need to reinstall.
