Question *HELP* HDMI NOT WORKING

[Joshua_82]

This problem first occurred after cleaning the GPU and reapplying thermal paste (did the line method). I installed my gpu on the pcie slot and installed it fine and proper. I plugged in the pcie plugs from the power supply to my GTX 970 evga ssc. I booted up windows and went to the desktop. The screen blacked and had said no signal. I had stable overclocks and overclocked my monitor to 75hz. The d-sub to dvi d adapter works plugged into the gpu, but it's hdmi that's not working. I used a different gpu and worked fine on hdmi but not the 970. any suggestions??

Can you get into Safe Mode? If so, see if you can uninstall the drivers and reinstall them with the latest off of Nvidia's support site. Might want to list your specs like so:
