Season 6 is crashing for me!

I keep experiencing crash issues. Ever since I started the new season, the game keeps crashing. Last season, I played with the same settings, and there were no problems. Now, the game crashes randomly, and my PC has even hard reset itself twice. I lowered the texture settings from ultra to high, but that didn’t help either. It crashed during ‘Infernal Hordes,’ and all my progress was lost. I’ve crashed about 13 times so far. I don’t know what to do. This has never happened in any previous seasons.
