Question PC starts up all fans spinning LEDs in the case working but keyboard doesn’t light up and monitor says no signal.

So I’ve been randomly having this issue for a while now off and on. Sometimes it’ll come on just fine and work for hours even running fairly graphics intensive games. But randomly it will freeze up or stutter both the screen and the audio and it’ll just turn itself off.. sometimes blue screen sometimes straight off. Usually if this happens when I try to reboot right away it will do the thing with the mouse and keyboard/ monitor not working but after a while it’ll come back on. The only error I’ve seen when it bluescreened was something about a video scheduler error. I’ve opened up the case and checked all my connections but haven’t done anything else.. any help is appreciated!

You really need to be more specific about what hardware you're using. At the moment all we know is it's a PC.

Is this computer running Windows? If so, take a picture of the next BSOD before the screen blanks out and tell us the STOP code.
