Question North bridge chipset failure

[Danny918273]

In about november I had a supposedly faulty motherboard cause it had a scratch on it (Asus SRIX B360-G), talked a bit about its warranty, sent it off for diagnostics and as they said repair(spoiler alert, they didnt repair it), after sending it, I got the same motherboard again, this time it lasted untill the start of april, it suddenly shut off when loading into FiveM, as I recently changed the windows and formatted the hdd, then reinstalled most of my stuff, the motherboard wasnt flashing as in a long pause then fast blink, so I thought it may be something else, apparently after a diagnostic, it was the chipset again. I would like to know what could make a chipset fail twice with the same components, bad luck twice or something else.
System specs:
I5-8500
Deepcool THETA31 PWM cooler
RX 580 nitro+ 4GB
Asus ROG STRIX B360-G
HyperX predator 8gb 2666hz

what do you mean chipset?
what the make and model of the psu?

I think I meant the north bridge chip, the one that controls the cpu.
My bad, forgot to mention the psu Chieftec proton 600w (it was also tested and it has no issues)

I mean how did you figure is the north bridge chipset? what is the issue?

The pc obviously doesn't boot, and I sent it off to one of my friends that work at a repair shop, they said its the north bridge for both motherboards, and in my country we dont have anything that could repair the north bridge, so if I get a new mobo, I'd like to know what I did wrong in the previous cases. Could be bad luck.
