Video Scheduler Internal Error BSOD

Good day

So this is a random error that has happened twice in the past 2 months but i have seen this error floating around the forums.

Twice ive started up D2R and after a few seconds of black screen i get a BSOD with “Video Scheduler Internal Error”.

Strangely on startup of the bnet app ive had to manually locate the install directories as when the app started up it said it couldnt locate any installed games.

Since the latest error ive started up the game with no problems. Is this a very random error that cant b pinpointed or this something very specific?

Any help would be appreciated.

Thank you.
