Hey there.

Recently, something happened. 

 

 

 

 

 

When I'm trying to render, during editing or while exporting using CUDA, I'm facing this error message:

I've faced it both rendering a 30 minutes at "mp4 Vimeo 1080P", and short 2 minutes sequence with the same encode settings .

 

Trying to render through Media encoder using CUDA either fails, or getting stuck at a certain point. 
I've updated my drivers, downgraded my drivers, Cache deleted, previews deleted, Media Cache Database cleaned, "Refreshed" Windows,yet, the same. 

The only solution I found is removing the GPU physically, and rendering. Which is painfully slow, and not efficient.
I've sent my GPU to the store, to check it under the warrenty, they have been testing it with programs and games (Not any Adobe program), and found it all proper. Currently the card is there.  

 

 

Only by the time getting home I thought about using DDU and trying to reinstall Pr. 
Any other ideas before sending my whole PC to inspection and paying 30$?

 

 

 

Thanks in advance.
