Brand new computer won't stop crashing.

Hi, I can't get my computer to stop resetting itself intermittently. This is a new computer I built myself. Whenever I browse the internet for more than a few minutes my screen goes black without a BSOD and the computer starts booting. It gives the windows didn't shut down correctly safe mode prompt. The crashes can happen anytime but are only consistent while browsing the internet. I've tried re installing windows and the event viewer tells me nothing. I've also tried monitoring my temps but nothing is going very high at all. The crashes are no more common under heavy load and I removed my GPU to see if the PSU was failing. Here are my specifications. Any help would be immensely appreciated.
