Screen randomly turns grey while watching live stream

[Bojan]

So im watching sodapoppins 24hour live stream today and been watching for like 12 hours and my pc's screen turned grey and there was no sound and i have to hold the power button too shut it off completely because it wasnt responding,this happened a few times today and it has never happened since i bought this pc,is it the stream or i dont know,the only thing i think may cause this is the new power cable i bought,it has 5 plugs and i think that might be causing it... (after it happens the computer works like it doesnt power down i have to shut it down by holding the power button)

It says "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."  Source "Kernel Power" and 3 times today,i think thats that i force shut downed it...

i had that problem for months. "0" means your pc has no clue why it crashed. what fixed it for me was new psu, but the power cable that you put in.. it might be causing that. i can't help you any further than this, good luck tho.
