Nvlddmkm error

reelyor

I was away from Studio over the winter. Coming back a couple of months ago, I installed (cleanly) 4.9.4 latest version. On occasion, while rendering in IRAY I experience the NVLDDMKM.sys error, with the screen blacking out, then returning after about 5 or 10 seconds. The render slows down, and then if I stop it, Studio crashes. I can reload the scene, and continue on.

   I have Windows 10 64 bit, GTX 970 Geforce, 16 MB memory, (5) case fans, Heavy duty CPU fan, and have cleaned out the NVidia driver using DDU and reinstalled using both the newest driver, and an earlier driver that I believe was workng OK after cleaning out the driver using DDU. Same problem exists in each case. I have just recently been able to cause it by opening another graphic program or looking at a saved render while actually rendering in IRAY. This seems to cause the error more often than not. I might add that I never had this problem with multiple programs before.

   I have gone online to search for this error, and it seems to be quite common in the gaming world, but I could find nothing with regards to Studio.

   Any suggestions? Thoughts? Remedies?

If I had to guess....  It sounds like your GPU may be going bad.
