I have a asus b85m-g motherboard but when i connect my usb keyboard and mouse they dont work and after turning on the pc the bios opens....so how can i boot windows?????
Try enabling the USB keyboard in BIOS setting, some bios have that. But im sure you can boot your PC without Mouse and Keyboard. Some tweaks on Bios might help.
sure you cant with bios, but with system its yes, how many usb devices are plug in ? idk maybe the USB power cant provide enough power for your devices
