I know hoa to get into bios but I don't know how to chsnge thingd from disable to enable, can u help me

LOL, had this issue many times before. Changing things in the BIOS is different for each type. One way is to hit down arrow to get to your selection, hit enter, then choose your setting. Another is to again down arrow to the selection, then hit page up or page down on your keyboard to change it. One thing you always have to remember is that you have to Save Settings then exit.
