I built a new system. A GA-Z97-HD3 with an i5-4440 quad core and 6750 Radeon card and a LSP Series 2 pro ATX 550 watt power supply. Ran a long time after building it ( 3 to 4 hours ) and then it started shutting down. Used PC Wizard to check temps and everything looked normal. Wasn't even gaming. Video card seemed to be working just normal. I even put my and in the computer after it turned itsself off and felt hardly any heat at all. Any ideas?
PS It now shuts down about every 30 to 40 minutes.
