I hav a computer that has its intergrated video card which stopped working because of the video card which is attached to the mother board .It is one of the newer post 2007 compact desktop computer with a flat screen monitor but the challenge is that the good friend of the family got an extension video card but it is too big to fit in that machine.How can I get a video card that will fit the above machine abovein which is a newer late 2000's -today.The operating system is vista.
