Hi wikaazz and welcome.

Which Windows 8 AMD Driver have you installed?

You could try installing Version 9.1 which is Windows 8 compatible. I don't know it if will fix your problem but it is worth a try.

You don't give your full model type so I can't give you a direct link but you will see the Version 9.1.9.1.0.0 under the Windows 8 Recent Downloads for the VPCCA3C5E available here:

This driver is available from Vaio Update - do you have this installed?
