Question My new PC keeps restarting every time I try to open Skyrim (and in other situations)

[birux]

Good evening.
One of my friends redirected me here and told me you might be able to help me, so, first of all, I thank everyone in the community for creating such a wonderful place for help.

Last week I finally built my new PC, this is my current setup:

My problem is, my PC reboots at the moment I open a game (tried with Skyrim and PUBG), between 10 and 20 seconds of the game, it reboots.
But problem is, it does it in other moments too, for example I was working for like 3 or 4 hours and it rebooted for no reason.

Here is a list of things I tried or I had to do:

• At first my motherboard wasn't compatible with my CPU and I had to update the BIOS for it to work.
• Unticked the automatic restart by windows. (also, first time with windows 10 btw).
• Updated all the CPU drivers, and pretty much all drivers with easydriver.
• Tried activating the overclocking but didn't understood much and it kept happening so I disabled it.
• Tried putting the minimum % of CPU usage in 5% and the maximum in 90% in energy options.
• Changed the RAMs to different slots.

Every bit of help is deeply appreciated, because I do not know much about hardware or tech, so a friend helped me building this PC. And my computer is my main working tool.

Thank you.

Little update: I've been told some info on the PSU is important here, I do not understand much about it, but I found these numbers on HWiNFO:

Thank you in advance!!

UPDATE

• tested memory and cpu, 0 errors.
• reinstalled windows.

I had a problem. It resets when I use the windows 10 "photos" app. Like, the picture visualizer.
I tried using it for rotating some pics but it rebooted every time. Like, I only could rotate one or two pics.

Had mo problem with adobe photoshop. Used it many hours without problems.

...i really don't know what to do.
