Computer turns off randomly

[Teedr]

For around a week and a half my computer has been turning off randomly whether I'm playing games or sitting at my desktop, and once it shuts off on it's own it will continue to shutoff 2-30 seconds after powering it back on. Sometimes the orange light on the mobo with flash repeatedly with the power button light, and when the power button is held down the two lights with flash really quick. In order to get my computer to work I will have to wait for 3-6 hours of leaving it alone in order to use it for the rest of the day, only to have everything repeat the next day.

(This is wile I'm using the EVGA 500w psu) This all started a week ago, I was in a discord call talking to a buddy and watching youtube. My computer suddenly shut off and when I went to power it back on 2-3 seconds later it turned itself off. I tried swapping the 1060 for and ATI x300se (256mb version) and unplugged everything except for 24 pin mobo, 8 pin cpu power, mouse, keyboard, dvi and, m.2. My computer booted into windows and worked for a while. I shut it off and put back the 1060 and everything worked fine so I plugged everything back in and it continued to work without shutting off. It worked fine for 2 days and it shut off in the middle of a csgo match, so I tried the same fixes like before and everytime I booted my pc it would stay on for 2-3 seconds and then turn off. I got tired of screwing around with my pc so I left it alone for around 9-12 hours and plugged everything back in the next day and it proceeded to work fine. For the next 2-3 days it would shut off on it's own and I would try to power it back on and it would work first try and I would use my computer for the rest of the day only for it to happen the next day. About 2 days ago it shut off as usual and wouldn't turn back on while I tried all of the fixes like before and it still wouldn't turn back on so I decided to order a 650w 80+ bronze thinking my psu was broken. I decided to try resetting my cpu thinking maybe something was broken, and no pins were missing nothing looked burnt or out of the ordinary so I tried powering it up and it didn't work so I tried a different outlet in different rooms I removed the m.2 boot drive and everything else and it didn't work I tried pulling the cmos battery and it didn't work . Yesterday I installed the new 650w psu and it worked for the rest of the day so I though I just had a faulty gpu. Today it shut off on it's own and I tried the same fixes like before and it didn't work. I tried the ram in slots 1 and 3 instead of 2 and 4, I tried 1 ram stick in all the slots. I'm out of ideas and fixes I could try except for getting a whole new computer. 

 

Sorry if this was all over the place I'm kind of losing my mind as I have work to do and I have been spending hours elbow deep in my computer.

Sounds like a broken power supply or board
