My PC will randomly go to a black screen. Capslock keys do not light up while it is on the black screen. Nor does any audio play.

It is not sleep mode because I have been actively been typing up documents before when it happened. I could be watching youtube and it will go black, or typing up a text document. It has happened mid game once.

Pls help.

The fans continue to run and all the LEDs stay on.

The only way to get the computer to return to normal is to restart it via the button on the front of the case.

once the screen is black you cannot do anything to it. no mouse cursor, no commands (ctrl alt delete etc) sound stops playing.
