I upgraded GPU from an AMD to another AMD, and my new graphics card is not recognized by Windows 10 in the device manager (not hidden devices either). The fans are spinning and leds are on, but if I plug my monitor to GPU, there is no signal. I thought first that my mobo didn't support the new GPU, so I upgraded mobo (and new case for mobo) with no luck. Today I upgraded my PSU to make sure power wasn't the issue. Still no luck.  I have clean uninstalled all previous drivers and other GPU software, then checked multiple times that there is no trace of any AMD software. When I attempt to install drivers from manufacturers site, specifically for this GPU, it hits with error 175, hardware not supported. Legacy drivers are not installing either. I have gone through my BIOS multiple times, but there are no options regarding PCIe slots or primary graphics devices.

My specs:

GPU: Sapphire AMD Radeon R9 280X Dual-X

CPU: Intel i7 2600 3.40GHz

Motherboard: Asus p8Z68-V PRO/GEN3 LGA 1155


Windows 10 home 64bit

PSU: Seasonic 750W

BIOS version: American Megatrends Inc. 3603, 9.11 2012


I can't find drivers fit for Sapphire AMD Radeon R9 280X Dual-X anywhere. Where could I find them? Or is my gpu just broken?


Thank you in advance!
