I just recently had a new PC built. Here is a link for the specs: http://pcpartpicker.com/user/marcd455/saved/4bCd since the moment it was put together (about a week ago) it has been randomly shutting down without warning. After the bootup it can either last for hours or only 30 minutes or so. Any advice will help, if you have any questions ask and i will respond asap, thank you.
