well i have this problem, if i use my computer a little too long or it happens faster if i play games, my comuter just ends up crashing and then just makes this constant sound that i believe is from inside the computer; and when i pull the plug the sound stops. so i really don't know what's wrong, i think it could be too hot and it just crashes because the fan could be broken, because i can't feel anything in the back of the computer. so could someone recommend what i should do? sorry this is so long
