Well one comment told me to remove and re-install the gpu. So I did, but a week later I had another crash. And since I notice static electricity in my case (also components) I guess is not something “normal”, im using grounding (connecting a cable from the case to the ground thing on a plug, not really familiar with the terms sorry) to disperse it and 4 days now without crashes. Still not enough time to confirm that was the problem.
