My pc keeps freezing with everyminer i use not just claymore's. I get this error in claymore
NVML : cannot get current temperature , error 999
NVML : cannot get fan speed, error 999 (something about an internal driver error)
If 1 gpu is in the rig it runs fine and hashes fine.

i7 5920k
MSI x99a gaming 7 mobo
20gb ram
MSI GTX 1070 8G
MSI GTX 1070 x 8g
SSD

Claymore 9.4
driver version i tried 368.81 and it started hashing at like 2mh/s then i did a windows update and it updated nvidia driver and crashed again.
did the 16mb virtual memory
Current nvidia driver crash too
stop the command prompt from quick fixing or something like that
changed the mobo pcie to gen 1

The cards are in the 1 and 3rd pcie slots

I reinstalled windows twice trying to get the freezing to stop. Have been messing with this for countless hrs If anyone could help that would be nice.
