If my graphic card fan is not running after placing in the pc...is it dead...display is not coming..all other components are working fine...please tell if graphic card dead or not...?
Have you made sure that you've plugged the 6-pin power connector from the power supply into the graphics card?
Your power supply should have no issues with a GTX 1060.
Try taking the ram out and putting it back in in the same color slots. Sometimes on Dells ive worked with the RAM has to be reseated. It shows the same symptoms as your machine.
