Hi everyone, sorry if the post is long. I'll explain the problem to you. First is that the motherboard LED remains fixed to indicate the GPU, and black screen, I turn it off/on from the power button and it starts normally. Before resetting the CMOS, disconnecting the battery, the situation was worse, if I deactivated the CSM it did the same thing and I have to do the same procedure. turning it off/on several times and the boot screen displayed "The GPU is not compatible with the UEFI drivers". On adrenalin then indicated, the settings were more or less reset.P.S. Now the error no longer appears, however I still have to do the procedure. I hope for help, thanks..
