Suddenly iRay won't work but Octane still works!

Everything was okay until yesterday. DAZ iRay couldn't find any GPU (still found CPU and can render normally). Log file said Found no Usable Devices. I've tried it with Octane and it still finds and runs my 3 GPU correctly as usual. Do anybody has any idea about this situation? Thank you!

    Did you install 4.9.3.166? That requires a newer driver than the previous versions. Alternatively, something may have triggered a system restore to roll back to an older driver. What you probably need to do is get a current driver from nVidia.

    Thank you very much Richard. After struggling hard all the day, I've found that I have to remove 980Ti and left just 2 TitanXs alone. I'm not so sure why, but this is working right now!
