It can be because of two reasons. The first is hardware failture; the second is software failture. If you have no problens with your hardware when you are playing games or doing something that requiring a lot of resources then you hardware is ok. In the case of software failture you have more choices to check. First, it can be anti-virus software failture which can be caused by a virus. If it's caused by a virus you have to use another anti-virus, for instance, free-av.com (they have free version). Second, it can be caused by an error in installation or updates you have to uninstall your anti-virus and try to install it again. If it didn't help you are welcome to ask more.
