Hi,
I installed a msi radeon 7850 into an hp pavillion p7-1210.
It isn't recognized by the computer and seems to have no power.
The Bios has no option to turn on /off the onboard video and the control panel search does not show a new video card.
Are there dip settings to turn on the card slot or somewhere else in the control panel or device settings?
