    Hi ljmcg, and a warm welcome to the forums!

    The fans are suppossed to run fast if it's overheating.

    Two things...

    Open Activity Monitor in Applications>Utilities... observe the CPU usage, report back please.

    Tried resetting the PMU?

    Safe Boot , (holding Shift key down at bootup), see if it still happens.

    please don't laugh but I was reading what you sent me " the shut donn things or what ever it was" and well its just thet my coputer is over heating as soon as I open it. is is because I dont chern it off? ok let me start from the begening I open my computer ist gets warm the fan is now on it keeps running no mater what and the bottom is getting hotter. I was downloading games off of big fish but now have taken most of them off in fear that it was just to much for my computer. and now I just dont know what els to do I read some of the stuff you sent and it doesin't make to much sense like I have no idea where all the keys are and what they stand for. unless it says what it does I have no Idea. I told you be for not to laugh. cause I know its silly but I have know Idea what to do...

    No, no, no, have no fear, when the student doesn't understand, it's the teacher's fault, not the student's fault!

    To help me understand, what part of the worlrd are you from and how old might you be?

    For a start, shut down the Mac for 10 inutes, then boot it up while holding the Shift key down... called a Safe Boot... does it still heat up, fans going on high still?
