Crash (Grey Screen)

Been playing for the last week and a half 40+ hours with no issues, then suddenly tonight when i start up the game im getting a grayish white screen that freezes my entire pc.

I’ve tried fixing this through online research seems to have been pretty common in the past, there has been no changes to my hardware/software this just happened suddenly.

I dont have any RAZER hardware/software, nor have i owned them

Things i’ve tried:

Fresh install
Scan and repair
drivers up to date
changing chroma effects to “1” in D3pref
Running game in 32 bit mode (this actually works for about 30-45 mins at a time but still eventually crashes and gray screen still appears)

Really frustrating that i cant play when everything has been fine for close to 2 weeks.
