Crash BSOD intempestifs même après reformatage

Bonjour,
J'ai des soucis d'ordinateur depuis deux ou trois jours; il me fait des bsod quand je vais sur le net ou que j'utilise des logiciels gourmands comme des navigateurs internet ou des jeux videos.
J'ai fait un formatage complet de la machine devant mon incapacité à régler ces problèmes, mais dès que je veux télécharger un gros fichier (exemple office 365), il plante à nouveau.
Avant le reformatage, j'avais fait une mise à jour de tous mes drivers, un scan ZHD de Nicolas Coolman aussi.
Il plantait particulièrement lorsque j'étais sur Facebook (d'abord j'avais un message d'erreur disant que la page a planté puis un crash BSOD) ou des jeux comme PUBG, ou encore quand je téléchargeais deux fichiers en même temps.

J'ai fait un rapport whocrash sur les deux derniers crash en liste:
