PC keeps shutting down in the middle of games

[voltsy]

So this has only started happening within the last week or so. My PC will just shut down out of nowhere in the middle of playing a game. When I'm just browsing the internet, or playing a low performance game like league of legends, it runs perfectly fine. This last week I recently started playing pubg, and within the last two days, it has shut off in the middle of 6 matches. I don't get any random frame drops, or freezes in gameplay before it shuts off, just one moment im looting a house and then it just randomly shuts off. I thought it might be because of system overheating, but as I have 4 case fans installed, I find it hard to believe it could be that.

My specs:
- i7-7700k CPU
- GTX 1050Ti GPU
- Gigabyte GA z270x gaming k7 motherboard
- 16GB corsair vengeance RAM
- EVGA 750W power supply

Just because you have 4 case fans does not mean anything for overheating if your CPU heatsinks is not on properly.

You have a K model CPU, is anything overclocked? If it is, set to stock speeds. Check temps during use using HWMonitor or another utility. Run Prim95 and check temps on that, run 3DMark see if the system runs that OK. Try one RAM stick at a time. Could be a failing video card also or power supply.
