I have a problem with my computer in the last few weeks where up to 4/5 times a day my computer crashes. There is a momentary freeze and the screen goes black and 'DVI No Signal' flashes up on my monitor. This has happened in Chrome, in games and when the computer has been idle so it is not an application issue. I am fairly certain that it's nothing to do with the monitor as if I press the Caps Lock button on the keyboard after the crash the light does not come on. Also if I am playing again the sound will freeze.
I am running Windows 10 Home on a Dell XPS 8700.
