I have a problem and to explain it short, Yesterday when I started my Asus laptop I got the message "pxe-e61 media test failure" and it just restarted. Couldn't get out of it so I went to bios and disabled PXE-boot something on Boot options. This I should've never have done because now when I start the computer it's just a black screen and it wont respond to anything. Does anyone know how do fix it? Reset bios and if so, how?
