I recently built my first gaming computer. After about 3 days of use it began to randomly restart. While playing games and while just simply browsing the internet. I checked to see if the CPU or graphics card overheated but it didn't seem to be that either. I restarted windows 10 and deleted everything and the problem still continues. Some days I'll play for 4+ hours and it won't restart but other days I can be on for 10 minutes and it'll randomly restart. I have also updated all drivers. I am not overclocking.

Specs:
EVGA GeForce GTX 970 04G-P4-2978-KR 4GB FTW GAMING w/ACX 2.0, Silent Cooling Graphics Card

CORSAIR RMx RM750X 750W ATX12V / EPS12V 80 PLUS GOLD

AMD FX-8350 Black Edition Vishera 8-Core 4.0 GHz (4.2 GHz Turbo) Socket AM3+ 125W FD8350FRHKBOX Desktop Processor

Ok. Assuming everything is connected properly, there are two most likely causes. Bad outlet or bad PSU. To test the outlet, I would recommend maybe plugging in something like a clock. If the problem is the outlet losing power, then if the clock resets to 12:00 you will know. However, the issue could be the outlet not handling the load of your computer. If that is the case, I am not entirely sure how to test it. An easier test would be moving to another room and using an outlet there, and checking if it continues to happen. If this does not resolve it, the most likely cause is the PSU.

Unplug all of your cables and then plug them in, making sure they are not flexing one way or another and that they clicked in. A similar thing happened to me when I first built my computer, and it turned out my motherboard 24-pin was not plugged in properly. I couldn't even tell by looking, and did not realize until I plugged it in again and the issue was fixed. What would happen is small vibrations from you barely tapping something could unplug and plug in a cable.

I tried this last night. Everything was working great. But then this morning I turned it on for about an hour and it reset again sadly.

I get a critical event when the power shuts off. It says Kernel power. Could it be a bad outlet maybe?
