    Hello @lse123,

    OK, as a start, here are a few things to try . . .

    [1] Take the casing panel off and check that the connections are firmly in place, especially the HDD/SSD cables.
    [2] There is probably a reset button on the Desktop, use a pen or something to push it it when turned ON.
    [3] Can you Boot into Safe Mode, I think it is continuously pressing the F8 key on an HP as soon as you turn ON.
    [4] Have you got an Installation USB that you could Boot into to see if that works.
    [5] UNPLUG everything except the Mouse and Keyboard and try.
    [6] Have you got ANY External HDD's/SSD's/USB's attached.
    [7] Have you got a CD/DVD inserted.
    [8] You could try replacing the CMOS battery.

    I hope this helps.

    I had a similar problem with an older motherboard. Replacing the cmos battery took care of it. A new one only costs a dollar at Walmart so why not give it a shot.

    It wasn't an HP. It was an Asus M5A97 but the same symptoms. At first I thought the board had failed but as soon as I swapped out the battery it was posting again. You could just swap the battery from another PC and see if it posts.

    I actually do have an HP with a core 2 quad! It's battery failed but it still would post. It just kept telling me the time was wrong.

    Hi,
    Probably bad hdmi connection
    Easiest solution is to try a vga or dvi connection

    Is it worth try
    Disconnect DVD DRIVE POWER
    REMOVE PCI DIALUP MODEM/FAX CARD

    RETRY to boot...?

    Again failure FINALLY

    I DO NOT THINK IS HDMI, Since PC Not boot, only fans listen, and hdd LED is off, also when press a key in keyboard is like did nothing... no LEDs light, i think may PSU is overloaded or CMOS Battery nedcs replacement...

    Hi,
    Pci-e card can confuse bios too.

    When it does this just remove and reconnect the hdmi cable on the pc see if it connects after.
