Hi guys, I'm lost here.

My laptop (warranty expired on October 24, 2016) is shutting down whenever I'm playing any game. Instant black screen, no error messages on bootup, nothing. I already repasted 2 times and changed the thermal pads once. My temps are ranging from 35C to 60C and when stressed, they'll reach 100C, maybe a bit past it. Already undervolted with ThrottleStop and my temps went down, so I know it's not a temp problem.

I have to note that my battery is dead and I have it unplugged, always, so my laptop is more like a desktop and is always connected.

When I repasted the first time, nothing changed, then the second time, I also changed the thermal pads. At the beginning I was able to play a few games that would shut my laptop down normally, but when I tried to play Valorant, it just shuts down. And now we're back to the beginning, instantly shutting down whenever I play any game. I did make sure to put a bit more paste than enough, but maybe I'm wrong. I'm using High Performance by Cooler Master and wondering if Conductonaut is going to make the difference, but with this I don't think it's a paste problem.

Can anyone help me, please?
