So, I had my problem solved for like 2 weeks and it started again, in event viewer it tells me that it's Kernel-Power 41, my laptop shuts down randomly when i'm playing games or when it does some heavy work, i'm not a geek, when it shuts down it goes with a instantly black screen and every process is down, nothing works, if I plug it off after the shutdown and I don't turn it on, it needs to be plugged or it won't start.
