First, i'm sorry for my english.
So, all was fine till I decide to play Monster Hunter World few days ago. There was an update and I started playing. In game, the pc crashed and rebooted. I thought it was my graphic driver so I updated them but nothing. So I thought it was the MH:W update and decided to go back to League Of Legends. And since this moment, LoL do the same thing. My computer crashes and reboots. Everytime I play. I tried to reinstall my graphic pilot with DDU, I reinstalled windows 3 times...but nothing worked.
I don't know what to do.
I didn't OC my GPU by myself (maybe stock OCed by AsusI think). I also disable the XMP profile...
Here my setup
Radeon RX 5700 XT - TUF GAMING OC - 8 Go
Ryzen 7 3800X Wraith Prism LED RGB - 3,9/4,5 GHz
X570 AORUS ELITE
HyperX Fury RGB - 2 x 16 Go - DDR4 3200 MHz
Corsair RM750, 80 Plus Gold, 750 Watt
and triple monitor display => AOC - LED 24" C24G1
Currently my graphic driver is 19.9.2
And windows 10 is my OS
Thank you for your help !
