Yes, replacing the display adapter is very simple. You just unplug the power supply, open the case, remove the cable between the display adapter and the monitor, unscrew the existing card, insert the new one, screw it back into place, close the case, reattach the cable and power supply. It really is that easy. I'm sure there are videos available on Youtube if you do a Google search. The only caveat is you should touch the metal case before touching anything inside the computer to discharge any potential static buildup (especially in a carpeted room).
