Help! This is my very first build. I am trying to access the bios but it won’t recognize my USB mouse or keyboard. I’ve tried all USB ports. I’ve tried using only one or the other. I’ve tried using a ps2 mouse (but I don’t own a ps2 keyboard). I’ve already installed Windows 10 and everything is working fine, so I don’t want to risk a bios update, but I need access to the bios to change my ram speed. What is the solution here? Is there another way to access the bios? Will a ps2 keyboard make a difference or a ps2 to USB converter? Any suggestions?
