I have a Dell 755 which had a new graphics card installed, however I do not have the adapter to plug my monitor into that graphics card and when I try to plug into the VGA of the motherboard I get an "unsupported video configuration detected" error (http://www.win-pc.com/wp-content/uploads/2013/12/Action-is-Required.jpg).
As I understand if I disable or remove the new video card I can use my PC from the original onboard graphics card until I manage to find the adapter but is there any way to do that without opening it all up and physically taking it out? I'm not so good with computers so would prefer to avoid opening it if I can. I've tried to get into the bios but for some reason F2 key doesn't do anything when I turn it on. :/
