Game freezes my whole PC

Hello, I'm here to report something that has been happening since friday on my computer and minecraft. Every time I play on a server (i.e: hypixel / mineplex) my game freezes and my whole computer stops working (including my keyboard/mouse), forcing me to restart it by pressing the power button. That should look like a hardware issue, but I have already updated all of my graphics drivers and checked my temperatures while playing. I've also tried to switch games and played CS:GO and GTAV (just to mention these ones) for more than 6 hours and nothing happened to my computer, but whenever I try to go to minecraft (I have tested 1.8.9; 1.14.2 and 1,13.2 vanilla), my computer crashes in approximately 10 minutes. Just to provide some more info, it's worth adding I have reinstalled my JAVA, have reinstalled my minecraft and deleted its previous .minecraft, have tested playing the game without java and have run viruses tests. I'm using the last Windows 10 update and I don't really know what to do since I'm pretty sure my hardware is not faulty, as I can play heavier games with no problem, and I don't want to reset my whole computer just to see if it stops breaking on minecraft. Hope you can help me, thanks!
