I have put all of my music on my pc and have it connected to my home system via Xitel device through the USB port. What I want to do next is install a new video card that has tv out so that I can set in my recliner and view my music files on the tv. My question is how hard is it to install a video card and do I have to go into the bios to deactivate the old video card which is part of the motherboard. The computer is a HP Pavillion 510n. Also any recommendations on a inexpensive video card with tv out?
