After updating to the most recent Crimson driver I tried switching my GPUs to turbo mode. The screnn suddenly had a yellow tint and a black screen occured. Since then I got a total blackscreen (I cant even see the UEFI ) and there is no HDMI signal even though the system is running.
I tried clearing the cmos, removed Ram, part testing etc..
How can I remove these turbo settings manually with no video output and hopefully resolve this problem as no parts seem to be faulty except those Crimson drivers lastly set to turbo mode?
