So just to understand . . . you have no graphics adapters showing in Device Manager . . . and yet you must have a screen display in order to notice that. What resolution is your screen currently using?
Did you install the drivers for the 5870?
Did the 5870s replace some other graphics card?
Is this a new build? And please tell us the rest of your configuration.
Hi it is a rebuild with a new hard drive. its running at vga adaptor. have it plugged into hdmi on mobo. Have not installed drivers because i have a new hard drive in it. This is a rebuild from a water build.
