So I just finished building my first ever PC (full parts list here: http://pcpartpicker.com/user/bgw0821/saved/1lZT) and I booted it up fine, it took me into UEFI and everything. But I am a noob and wasn't sure what I was looking at at first, so I powered the computer off in order to restart and make sure UEFI was the same thing as BIOS. But when I turned my computer back on, pressing DEL for BIOS/UEFI, nothing came up on the monitor and the Dr. Debug window shows the code Ab(A6?). If I boot the computer up without pressing delete, the code is A2, but as soon as I hit delete it goes back to Ab. If I unplug keyboard/mouse (from their USB 2.0 slots in the back) and boot then I get d7, which is just telling me to plug them back in. If I plug them back in, I get 64. Don't know what that is but it goes away when I restart the computer and A2 comes back. I've tried using onboard graphics with DVI and HDMI cables and I've tried a different monitor. Not sure what to do now. Any help would be greatly appreciated!
