Here's the problem I'm having - recently my computer has stopped using the video card and only uses the on-board video for the primary display. Since there is only one monitor this really sucks. The card is a GEForce 8400GS yeah I know not great but vastly better than on-board. I've done a system restore, re-installed the driver, un-installed both and re-installed again. Primary display in bios is set to pci but even the diagnostic boot screen only show on the on-board. It shows the card as installed with no problems. With the cards output set to the secondary display I can manually change the input on my monitor and it displays just fine. I don't game much but the on-board video is so bad it won't run anything. I've tried everything that I could think of or look up except ask here, so now I'm asking.
Thanks in advance for the help.
