    Default Mobo prob -Video output is not detected after reset of initial boot

    Hello, all!

    I am working on a home build computer with a:
    Ultra LSP 550W PSU
    ASRock M3A770DE mobo
    2x2 GB RAM
    Sapphire Radeon 6850 HD [COLOR=blue !important][COLOR=blue ! important]graphics [COLOR=blue ! important]card[/COLOR][/COLOR][/COLOR]
    AMD Phenom II 955 processor

    Here is my issue:

    Having just built my first computer, I power it on and it boots up. However, I accidentally placed the mobo disk in the drive instead of my OS disk. It asks me if I want to create a SATA(?) diskette Y/N, and I find out that my keyboard does not work (this might sound ridiculous, but it's actually an [COLOR=blue !important][COLOR=blue !important]apple [COLOR=blue !important]keyboard[/COLOR][/COLOR][/COLOR] that I placed in the USB drive just to experiment, I suppose that it shouldn't surprise me that it didn't work).

    So I pressed the reset button, and my computer resets; this is where my problems begin:

    Now, nothing shows up on my monitor. It says that 'video output' is not discovered, as though it was not hooked up right and yet nothing was changed. I breadboarded the whole thing, checked all my connections and cables, tried resetting the bios, I have disassembled and reassembled - and nothing is different. I have no idea as to what to do right now, as nothing is different. Why, all of the sudden, is there no video output on my monitor?

    Hope you get an answer as I have a similar issue, black screen - no VGA signal found.

    Two questions come to mind;
    1. When you say "reset" do you mean you cleared the CMOS or did you press the reset button?
    2. Did you try another keyboard?
    Asrock Z68 Extreme 4, i7-2600K, DH-14, G Skill F3-14900CL9D-8GBXLD, HD6970, HX-750, 3X 2TB Hitachi SATA3, Corsair F60, etc
