Completely random restarts?

[Moogle55]

So I just finished building my computer, and now after a little bit of use my computer starts to random;y restart itself. I disabled the feature to turn back on after a blue screen, but it still restarts and doesn't give me any info on a bnlue screen... In the event viewer I get a message that says critical, and something about kernal-power , event ID 41. On bluescreenviewer i've been getting them sometimes on restarts, but the most recent one is caused by dump_dumpfve.sys but I don't get a message on there usually. Any ideas? e.e

edit: also I get this error quite a bit in the event viewer, not sure if it's connected though.

The program LiveComm.exe version 17.5.9600.20605 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Action Center control panel.

I'm assuming you've already done stress testing and that you're sure it doesn't overheat. If nothing else comes up in event viewer then the shutdown was not initiated by the OS (critical software error). The error about kernel power is just warning you that the caches were not flushed and the shutdown was not proper. I'm thinking bad hardware. Specs?
