I'll begin with my spec: Ryzen 1600@3.6ghz, MSI Armor 1080 8gb, 2x8gb Corsair Vengeance 2133@2666mhz, SilentiumPC Supremo M2 550W(you might not know the brand, but it's a really solid PSU with 80+ Gold rating), Phanteks P400S TG.
Yesterday evening my PC 'shut down' when I was playing PES2018 Lite. I've used '' because I'm not sure what actually happened - my PC seemed to be working, fans were spinning, lights were on, but my screen and speakers lost signal and my mouse and keyboard turned off. Also, I've tried waiting some time but nothing happens - it just stays that way, so it isn't saving power or anything.
That was not the first time it did that - I can't remember the first time, but it crashed 2 times when I tried to open Android Emulator for Visual Studio.
At first I thought it's the PSU's fault, maybe it can't keep up with the rest of the components? However, I've played multiple demanding games(including a very heavy Nintendo Wii U emulator running Zelda BotW) with no problems and I doubt Android emulator or PES2018 are more demanding.
My second guess was CPU - I've got it overclocked to 3.6ghz on stock cooling, but that's a very safe OC and the temps are pretty good - nowhere near the limit of the CPU.
Third possibilty is RAM. I've had an issue in a different PC that crashed when I filled one RAM socket and it tried to save memory to the other socket which was faulty, but then the PC shut down completely, not kinda shut down like this one.
To be honest, I've got no idea what's causing this problem and how to troubleshoot it, any help would be appriciated.

does your pc still work? or its technically dead atm?

specs?

run event viewer and it will tell you what the critical error(s) in a box in the middle of the window.

post what you find there, if you dont google the codes yourself (though i would suggest you google the codes and fix it faster than waiting for a reply)
