The laptop is pretty old, it might be overheating.

I've taken it apart..redone the dielectric grease..she's so clean you can eat out of the inside of the case,no matter what I do she does get pretty warm..I now run it on a cooling pad with the ram door off(works pretty good)I don't think I can do anything else to run it cooler besides throwing it in the snow.
