Cant find motherboard/usb drivers

That motherboard appears to be from an HP Pavillion m7580n.
If so, all of the original drivers for that motherboard are right here: http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=228&lc=en&dlc=en&cc=us&lang=en&product=3189598 .
It's about 3/4 the way down the page in the "Original Drivers" section.
Look for the "nVidia Chipset Drivers".
There are also all of the other drivers for various integrated components, so make sure you get what you need.

Hope that helps.

p.s. - If you aren't using Windows XP, go here to choose your Operating System: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=3189598&lc=en&cc=us&dlc=en&lang=en&cc=us

thanks but i already visited my hp page.. (it was a a1610n hp though). After installing my chipset drivers, the usb didnt install. When gaming with FPS, the mouse is very innacurate
