    Default FM2A75M Pro4+ Build - No video output, no POST beep

    Hi Everyone,

    I'm running into some issues with my build - I'm unable to get any video output from any of the ports (VGA, HDMI, DVI) from the motherboard.

    My setup consists of:
    FM2A75M Pro4+
    AMD A4-5300 APU
    Hynix 1GB RAM

    I'm also not seeing any POST beeps either. The CPU fan, the case fan do turn on and run, but nothing else.

    I did find this at one place: Product review of ASRock FM2A75M-ITX mITX FM2 AMD A75 FCH DDR3 1PCI-E16 SATA3 HDMI D-Sub USB3.0 Motherboard
    not sure how relevant that might be.

    I've tried 2 different versions of the APU, 2 different motherboards (same model), 2 different sticks of RAM, 2 different PSU's.
    I'd appreciate any input into this.

    Thanks,

    -R

    Is this while feeding a television, or a computer monitor?
    #1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.
    ____If you are overclocking, underclocking, or undervolting any parts, informing us of this and their values would prove beneficial in helping you.


    #2 - Consider your PSU to be the foundation from which all else is built upon. Anything built upon a weak foundation is poorly built.

    On the MB itself, to the left of the SATA ports should be a white sticker on the BIOS chip itself.

    What's printed on this sticker? It will be the BIOS release/version the board originally came with when new. Seeings you can't enter the BIOS this will inform us of the BIOS version. Or you can use a uttily like CPU-z too while in (?)Windows(?).

    The sticker says:

    P1.30-15A

    Hmmm........

    Three things I'd look for/at.

    1. Check that there are no extra/misplaced standoffs under the board that may be causing a short.
    1a. Also check the rear I/O panel filler that one of the "tabs' isn't finding its way into one of the rear i/o ports and shorting there either.

    2. Check that whatever heatsink you're using isn't shorting out against anything/anywhere. Front or back of the MB.

    3. Maybe should have been 1st, but if you have a friend with some memory that you can test with too. Yea, I read "2 different sticks of RAM" but w/o knowing what two I'd still pursue this as maybe being a memory related issue.
