I have a dell XPS desktop windows vista, its a few years old. My problem is when i power up the computer, nothing comes up on either of my screens. The fans keep running and there is a loud continous beeping coming from the nvidia graphics card i think. It was working fine earlier today I'm not sure what the problem is
I uploaded a video showing exactly what the problem is
