I've had my Radeon HD7770 GB OC Edition 1GB for maybe 3 years now. But it suddenly stopped working. The motherboard I'm using it on is a GA-Z170-D3H. It's in the first PCI-E slot, and the 3pin power connector is properly connected. In the BIOS the initial display output is set to the PCI-E 1 slot, but I get no output whatsoever. I'm using a HDMI cable to my monitor. The monitor or the cable are not the problem since they work with the integrated HD530. The fans on the GPU are working, but there's no output.

Any help would be greatly appreciated.
