Hi guys I have used integrated graphics card for a month. After that I put back Sapphire HD 7790 Dual-X in the rig and now I can't use it. It begins to spin at max RPM and everything goes right until end of windows charging. After that there is only black screen. Tested on two separate systems, both runs great on integrated graphics and bad with that VGA. When it were took off it were placed not safety but it doesn't looks like it were damaged. No possibilities to use RMA. How to fix it?
