I have a new Samsung Laptop running windows 8 on 64-bit, with an Intel i7 core processor, it has 8GB of RAM and over all works very well. Recently i have found how ever that i continue running into a problem, after a bit of playing a video game my computer totally shuts down and i have to restart it. The two games i have been playing lately that cause this is "Rust" and "War Thunder". Ill normally be maybe 15-25 minutes in game and the computer will just totally go black. I've tried just about everything i can think of to fix it on both games, reducing the graphics, shutting down all other programs and windows, v-sync on, deleting and re-installing both games, but the problem continues. I remembered however after getting this computer that when i tried to play Minecraft the same exact problem would happen, I fixed this by getting Java-64 rather than 32 and the problem went away completely. How ever if i'm already running 64 why would this still happen with these other games? I'm 99% positive it is not over heating since i always check and the laptop is no warmer than it normally is and like i said i try to make sure no other programs are running in the background. This never happens with anything else and i'm very confused on the matter, your help is much appreciated!
