hi. i have a problem with my computer. whenever i run a game, a game of anytype, the computer will freeze. the games can range from starcraft to diablo 2 to rainbow six. my computer will always stop responding. also, i have to have the case off of my computer. if i leave the case on, then the computer won’t even startup and will keep freezing when it starts up. this makes me think it’s aa overheating problem, but whenever i check the inside of the computer, the components seem fine. any and allhelp appreciated
