When I push power button fans turn on but all appears is black screen. After a while fans turn off and on much louder. After disconnecting all unnecessary and plug in external monitor, issue remains on the screen "no bootable device" appears, but still no boot screen. After connecting bootable usb flash created with media creation tool still no response. I tried change RAMs slot CMOS battery change, but still the same. All I need to is get in Bios, is there anyone with same problem?
