(I than plug it in while holding it down, than have to Restarting the computer in order for it to work. ) any suggestions? If it's hardware, how do I fix it?

    Sounds like a classic dying power supply. Check to make sure all power and video connections are secure inside and outside, the graphics card is seated properly, and that your monitor cable isn't faulty.
