Go to the Sony site and get the latest video drivers from Sony for your laptop. That's what needs to be installed.
If your laptop or desktop's hardware is an X300 chip I don't know that you'll be able to install "retail Catalyst drivers" for a standard "retail ATI video card". As you've seen, it can claim to be installed successfully but somehow never really gets attached properly to the hardware. Something about the "Mobility" version of Radeon hardware that does not allow the main Catalyst drivers from being installed. You need "Mobility" drivers.
There's something very odd about these OEM installs of Windows, in terms of what the manufacturers do to them somehow to actually prevent "retail Catalyst drivers" from being installed.
The only way I think you may be successful is if you erase C and install a brand new "retail Windows 7" from scratch. Then the hardware will be detected, and a retail Catalyst driver package will work. But with the OEM version of Windows somehow there is a lockdown.
Note that this also happens with desktop machines. I've now seen exactly the same thing on both a new Compaq and Lenovo desktop machine, both of which have modern ATI video cards (an HD540 in the Lenovo). Both have triggered automatic Windows updates but only going to 11.2. You cannot install a newer Catalyst driver downloaded from the ATI site and have it "work", although it seems to install properly. The drivers shown will still be the ones provided by Lenovo out-of-the-box, or automatically updated with Windows Update.
At least that's been my experience fighting with this very issue over the last few years. The only real solution is to eliminate the OEM version of Windows 7 running on the hardware, and install a retail Windows 7. Then you can do whatever you want.
EDIT: just noticed that your Sony Vaio is a desktop machine, not a laptop. But still... based on my similar experience with Compaq and Lenovo desktops and the same issue of wanting to install more recent drivers than 11.2 for the ATI video hardware in both machines, it just does not work with the OEM copy of Windows 7 that's installed by the manufacturer.
