Occasionally I will be using my computer and all of a sudden I hear a click and it seems as if my hard drive shut down. My screen freezes and I can't do anything except turn off my computer. The fans and everything seems to be still running too. When I boot up there is a message saying "The system has recovered from a serious error." After that the computer seems normal until it does it again. It's not very consistent and has been doing then from as short as a few hours to as long as a month. Any help would be appreciated. Thanks!
