PC Randomly Shuts Down.

Story, so everything was fine last week until the 28th April, I got a random pc shut down, at the time I thought to myself probably some power area problems since it's common around my area and I shrugged it off. It rebooted normally and I was playing fine for like couple of hours with no shut downs. The next morning, I was just light browsing reddit and it happened again, same thing, no BSOD, no errors, just straight black and rebooted back normally. Then it happened again and again, at seemingly random intervals, sometime I can go 2-3 hours with nothing and shut downs. Sometime 20 or 30 minutes it'll shut down.

 

Things I've tried so far is

Unplug and replug all my psu cables. Yes I've made sure it's as tight as it should be.

Second is running memtest, using my own stick the memtest first run randomly shut down, but passed all the test 4 times/pass during a 2nd run.

 

Also tried sticking the RAM stick on the other slot and it seems my other RAM slot is dead. Borrowed a friend RAM stick and it didn't detect the 2nd slot RAM. I'm currently dumbfounded and any help is appreciated.

Have you tried different PSU

Don't have any extra psu lying around, might bring it to local pc shop to diagnose later.
