Strange issue

Hi,

just had a very strange issue.

Today in the morning, no signal would come out of my RX580.

I tried almost everything (hard reset, disconnecting power, checking monitor, cables, different outputs, etc) and when I was about to give up and plug in my older GT 740, I remembered the RX 580 has a dual bios and a little switch.

I switched to the second bios and voila!, my hackintosh was back alive.

Then I decided to turn it off and switch back again to the primary bios, and voila!, back to normality.. or not..

Anybody has had a similar problem?

Thanks!
