Specs:
CPU: 6700K

Mobo: MSI Z270 M5
RAM: 16GB DDR4
PSU: Corsair HX850i
About 2 weeks ago I came back from a holiday and tried booting up my PC. It didn't do a thing. I knew it wasn't likely to be a PSU issue as the clear CMOS light at the back of the case was lit up however I still spent a few hours testing the PSU on another machine where it performed perfectly. I tried unplugging components but still nothing. I then decided to remove the CMOS battery and replaced it with a new one an hour or so later. It booted up. So 2 weeks pass and I'm playing a game when it just randomly turns off, then on about a second later, then off and does this about 10 times with varying times between before it stops, powered off and refuses to boot just like before. I removed the CMOS battery like before, waited about 20 minutes, put it back in and it stayed on for maybe 10 minutes before it did it again. Usually I love a challenge like this, finding the issue and fixing it but I'm now just extremely stressed with exams coming up and my code on the PC, I feel like I've tried everything and I'm just stumped. Any help at all would be massively appreciated.
