Hello, I activated accidentaly the intagrated GPU option in bios when my CPU doesn´t support Intel graphics. Now I can´t access bios cause the black screen. I´ve tried to clear CMOS in different ways but ii didn´t work. There two jumpers in the mobo (Rom_Recovery and Clr_Cmos) I´ve tried moving jumpers but no success, the manual isn´t clear about it. Thanks in advance.
