While using GPUTweak, I pressed on profile #1 button (on the lower section of GPUTweak). My computer rebooted instantly and since then my Matrix 580 isn't detected by windows, and I can't get an image while booting. It's like if it was dead, but physically it looks ok (lights and fans are on).
I never configured the overclocking profile, so I don't know what settings were on that first profile (my mistake to click on it..). My second card (i use SLI) is a gigabyte 580 and still works fine.
I tried to use the safe button (holding it until i get to windows), but the side led doesn't light up like I read it should. When I get to windows, the card isn't detected so GPU Tweak doens't try to reset the Bios.
Is there any other way to get the default settings back? Am I using the safe button correctly? Any tests I should do to verify if the card is still functionnal?
