Client crashing

I was playing and suddenly the game crashed, no error message was displayed. I was in the middle of a match.
Here’s my DxDiag: https://pastebin.pl/view/6238eedc
Both Windows and graphic driver have been updated with the most recent versions.
It’s also happening to me in Heroes of the Storm, I had to stop playing it because it’s happening so frequently.
I have not had this problem with other games, like WoW or games from other companies.
Any help would be greatly appreciated.
Thank you.
