['puter gunna die]

My system has been shutting down abruptly since I built it a month ago. Without warning, it goes black on me and starts back up. My PSU is a new Antec; I don't suspect it of being defective.

So I opened event viewer:
"Critical: Kernel Power: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

Next event was:
"Information: Kernel Power: ACPI thermal zone ACPI\ThermalZone\THRM has been enumerated.
_PSV = 0K
_TC1 = 0
_TC2 = 0
_TSP = 0ms
_AC0 = 0K
_AC1 = 0K
_AC2 = 0K
_AC3 = 0K
_AC4 = 0K
_AC5 = 0K
_AC6 = 0K
_AC7 = 0K
_AC8 = 0K
_AC9 = 0K
_CRT = 400K
_HOT = 0K
_PSL - see event data."

After that is:
"Error: Event Log:
The previous system shutdown at 7:07:42 PM on ‎3/‎10/‎2013 was unexpected."

If anyone has any suggestions as to what the F&$@ is going on, let me know. See attached jpeg.
