Hi there.
Sorry, i wanted to include this part to my previous post but i spaced it.
If your CPU is a clone the startup screen may identify what brand and board number if you are lucky, otherwise you may have to open the case (you only need a medium phillips + screwdriver) and look for the p/n, many are like this:
P4PE
or
P5S2-ATI Rev1.1
Then you go to the manufacturer's web site ex "asus" @
www.asus.com and fund the driver d/l page enter your bord # and OS and download all the drivers and install them.
Then do the same for all the other cards that are in the CPU A flashlight might be usefull.
