Random Shutting Down +hijackthis Log

Hello, toshiba laptop is in a weird habit of randomly shutting down as of late. Might be a problem with the heating, but purchased a laptop cooler and it doesn't seem to alleviate the problem. Was wondering if there was anything malicious running on it so decided to ask for help here. Thanks in advance.
