Having an issue, not sure how to troubleshoot it. I've formatted a new rig with 1.4 and updated it with 2.0, its loaded with EVGA Hybrid SC2 cards and I keep getting this error every few hours

Code:
Unable to determine the device handle for GPU 0000:02:00.0: GPU is lost.  Reboot the system to recover this GPU


Fri Feb  9 03:49:35 EST 2018 - reboot in 10 seconds
Fri Feb  9 12:03:26 EST 2018 - Lost GPU so restarting system. Found GPU's:

Every time watchdog fails to complete the boot and when I turn the screen on it just shows a thin purple line at the top and a black/blank screen


Thats a frozen rig with failed GPU.
Could be riser problem, Power or high OC.

I had the exact same issue. I was getting where it couldn’t find the device every 36-48 hrs. It wasn’t an overclock issue or a bad riser. Once I updated to the newest miners the issue seemed to have worked itself out.
