Im not the best with chipset ( motherboard ) drivers but I dont think that you have your installed or some are missing for example under display devices
AGP Status: Not Available
is listed which suggests that your card isnt being read properly. You will need to find out what drivers to download from your motherboard manual. Your machine states it is nvidea so you will be able to find and download the correct type from their website. http://www.nvidia.com/content/drivers/drivers.asp under Platform/nforce drivers.
It will probably be the nforce1/2 or 3 or 4
Hopefully Rog will check this to confirm my suspicions
Once that is fixed lower your sound acceleration by running dxdiag, click sound tab, move slider to left until it says basic, exit.
Also you are running your monitor at 60hz. If its a CRT then you should raise this to 85Hz in display properties , if it if a TFT flat screen then this is OK leave as it is.
I am at work so cant check your video drivers but you should download the latest from ATI - just download the driver set and not the full catalyst set if you are happy with ATI tray tools.
I would raise AA and AF to 2 as this will improve your images, then try 4 to see if this is ok or hits your frame rate too much.
I would expect you to be able to play in the low to mid 30s av in black death with your system
IF I have time tomorrow I will check your specs more closely but if not then pm rog and quazi to have a look as Im on holiday so cant follow this up as quickly as I would like to
good luck
