Hello,

I have just completed a build with the below components, and while it works great for the most part, it has been restarting randomly with the below code in event viewer(Kernel-Power 41 (63)):

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

This usually happens after ~45 min of heavy gaming, a few seconds of prime95, ~5 minutes of heavy GPU bench-marking, as well as randomly every few hours while idling.

I have the below components and have installed the latest drivers on my graphics card.


CPU: Intel Core i7-4790K 4.0GHz Quad-Core Processor ($339.99 @ Newegg)
CPU Cooler: Noctua NH-D14 65.0 CFM CPU Cooler ($74.99 @ Newegg)

I have used the "Intel Processor Diagnostic Tool, which gives me a "PASS" in all areas, and I have used the memory diagnostic tool with no problems.

Additionally, I have used HWMonitor and the temperatures seem to be somewhat in the normal range.

What could be the culprit of this Kernel-Power issue? Is this a power supply problem? Are there any other tests I can perform to find the culprit?

Thank you for any help!
