Had the same issue yesterday, for me it's the GPU
I'm using AMD RX 580
What I did was clean the contact pins with 99.7% alcohol and remove the old thernal paste then apply a new layer of thermal paste

After that, the GPU is running fine again, even did a stress test for 24 hours non-stop, no crash whatsoever

hmmm i wonder did i put too little thermal paste last time xD
at least da temp was kinda good.. 60ish.. will try it after dis..

one more thing to add, this started to happen after i updated win10.. donno if it matters much..

btw, how do u know its gpu prob?

🤨
I just told you why

chill bruh haha... what i mean is how do u narrowed it down to gpu dat coz da problem? u clean it and its good?

sorry bruh.. im still learning n really interested in prob diagnosis xD

Because when the screen goes black, suddenly the GPU fan runs at 100%
So I took out the GPU and checked the GPU thoroughly

Then I found out the contact pins was dirty & the thermal paste has dried up

oo.. now i understand.. thanks for sharing dis knowledge wit me bruh ))
