My GPU won't post even though the fans are spinning

[diekerrs]

Hey guys! I installed a Watercooler for my CPU recently(masterliquid 120 lite) and now my GPU (Powercolor RX 480 Red Devil) won't post, even though the fans are spinning. The ezdebug debug less for CPU and Dram are on, the one for GPU isn't . I tried switching the PCI power plug but that didn't help either. My MOBO is the MSI b350m gaming pro and my psu is the be quiet! system power 8 500w. Any help would be appreciated!

Reset the bios to defaults.

Unplug the PSU, and use the jumper on the motherboard or remove the battery for a few mins.
