i have a asrock z77 extreme4 with a intel i5 cpu. New build. i start it up no video, no post nothing. i get the code A2. So i change my ram to different slots, remove my video card, cmos clear, remove sata cables to dvd and hdd and still nothing. i can't get any thing no bios nothing. everything is brand new. Any help would be great thanks
