Welcome to the forum!
First of all, you should be able to adjust the color quality under display properties in the Control Panel.
Or just right click on your desktop and go to I believe it's Properties (haven't used XP in a while).
It is advisable to install the SM Bus Controller driver.
The AMD All-In-One driver will auto detect your system components and install the appropiate drivers.
You can actually get the AMD All-In-One driver from any motherboard website:
