I recently bought a Ryzen 9 5900x with an x570 mobo. It worked perfectly for just over 6 months and now not a day goes by without at least crashing just once. In tests, the pc does not present any type of problems or errors, but if I open a game and at the same time a browser or stream on discord, it lasts not even 15 minutes, it simply restarts without warning or error. I already changed the PSU, two different set of memories and even the VGA. Nothing solves or gives any clues.
I've already updated all drivers and BIOS to the latest versions and nothing has changed.
Specs on the CPU-Z image.
The PSU is an XPG core 1300 and although the image shows a GTX1080, I have an RTX3080 ti and both show the same thing.
I need some help, because the warranty is about to expire and I'm out of ideas.
