My PC restarts randomly

[patorrojo]

For about 2 months or so i've been having this problem. My pc restarts randomly: playing games, browsing youtube, chatting on discord... I can't find any cause!
i've swapped my PSU TWICE from 500 to 750 W and im pretty sure 750 is enough for my system.
Temperatures are stable and not even high, i've tried disabling the auto CPU overclock, ive plugged more power to my motherboard, nothing works and im honestly running out of ideas
My specs are the following:
AMD A105800K
8GB ram ddr3
Nvidia GTX 1060
Gigabyte F2A88X-D3H
Samsung 250GB SSD
500 GB HDD

I appreciate any kind of help someone can give me, its really annoying and im worried that my pc is gonna die soon

Can you type and enter this command in the start menu. perfmon /rel

It will open crash reports. Find one of those random restarts and paste the content here if possible.
