I've opened up my computer's case and found no video card so I've been told that my video card is built into my motherboard. I was then told to buy a new video card and insert it into my computer's pci slot then hook my monitor up to my new video card. I have no idea how to do any of this and I have no computer knowledge so I was hoping someone could give me step by step instructions as to how I should undergo this whole process or if they know of a video link that could show me how to do these things. Also, would I have to somehow remove the video card that is supposedly integrated into my motherboard or is it ok to leave that there and just install a brand new bigger video card? Thanks ahead of time for any feedback!
