Hello, i was playing the new space marine for about 3-4 hours and the laptop suddenly shut down (im guessing due to overheating) and it won't turn on again. Would appreciate any advice 

Hello, I was playing the new space marine game, and it was running fine for about 2-3 hours. After that it suddenly shut down, after leaving it for 20 minutes to cool down it won't turn on again. Would appreciate any advice 
