I have replaced the MOBO and PSU. Im runnning a 1500W psu for 1 1080ti. I am still getting the following errors:

ERROR QUERYING DISPLAYS ON GPU0

ERROR QUERYING CONNECTED DISPLAYS ON GPU 0

ERROR RESOLVING TARGET SPECIFICATION 'GPU0' (NO TARGETS MATCH TARGET SPECIFICATION).


NONE of the OC settings work for my NVIDIA cards (that work fine with awsome miner and afterburner). The rig mines but the cards overheat and there is no overclock. NVIDIA-SMI command shows the card is recognized, in use, and using 186W of 200W. One of the admins said it was a power issue but I  don't see how. Anyone have this problem before?
