Turn off computer.
Remove the 7950, plug monitor to motherboard.
Boot into windows, remove all graphics drivers. Run a driver cleaner.
Go into bios, disable on board graphics. Make the first boot graphics device "PEG" or "PCIE".
Turn off computer.
Install the 7950, plug the monitor to it.
Turn on the computer.
Go into windows, install the drivers for the 7950, profit.
