Not a clue what caused it, or how to find out. Happened once in the ~2 months I've had this new PC (specs below), nothing shows in WhoCrashed (no dumps), and this is all information in Event Viewer, seems pretty generic/uninformative. No hardware/software changes recently, occured while playing WoW, just a complete computer lock up, no sounds/bsod or anything.
Intel Core i5-4670K 3.40GHz (Haswell) Socket LGA1150 Processor
Gigabyte Z87-HD3 Intel Z87 (Socket 1150) DDR3 ATX Motherboard
Seasonic G series 550w '80 Plus Gold' Modular Power Supply
(Forgot the RAM I have atm) (2x4GB)
Corsair Carbide 200R Compact ATX Case - Black (CC-9011023-WW)
CoolerCooler Master Hyper 212 Evo CPU Cooler
MSI Radeon R9 280X Gaming Edition OC 3072MB GDDR5 PCI-Express Graphics Card
Event Viewer - Application - Error "Source: WMI"
Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.
Event Viewer - System - "Critical / Error"
The previous system shutdown at 05:22:14 on 09/02/2014 was unexpected.
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
Guess I should just write this off unless it happens again?
