I have many setups in the field that are running the GA-Z97X-Gaming G1 and i7-4790K not over clock. Actually been under clocking to 3.7 Ghz with no Turbo boost to keep temps down with stock cooling. After systems run in field for couple of months, turn off system for night, come back in morning system acts like it is dead with now power. If you unplug the power supply from system and pull off case side. When you plug power supply back in, red power button lightat top right hand corner of motherboard will show for a second and flash off. System will not start, acts like a bad power supply. If you take out CMOS battery and let sit for 5 minutes put battery back in, system will power on no issue. Or if you turn the battery sideways and touch the connectors in the battery socket to short will start no problem. Usually once this happens one time never will happen again. Any Help with this matter would greatly be appreciated! Thank You for the time!
