my radeon HD4850 doesn't appear to work and it is my CPU who does all the rendering. It is detected indeed, but CCC "don't recognise a driver". I installed newest lucid virtu first, just after chipset drivers and so on. Then i installed newest catalyst. What did i do wrong? My board is asrock extreme 3 gen 3, cpu i7 2600.

And second thing: why my os does not see an pci card (sound blaster audigy 2 zs) which is installed?
