  1. I have put together a new pc. Its a intel 6400 paired with a msi 975platnum revision 2 motherboard, 1gb stick of ocz 4-4-4-12 ram and a 600w Silverstone psu.
    Booting it up the fans spin up for about 5 secs but theres no beeps or any screen activity, it then shuts down.
    Tried a old backup 480w psu and it wouldn't even turn on.

    Taken it all apart and checked its all in the right spot, reset the cpu and made sure there was nothing loose.

    Starting to pull my hair out, have I bought some busted parts or am I missing something simple?

    Any help welcome:)

    Place the mobo on its antistatic bag and try powering it up outside of your case with just processor (+heatsink), graphics card, and ram in it.

    I had the same problem

    Hi I had the same problem couple days ago.

    After 3 days of searching here's my solution.

    Your CPU is a new generation of CPU
    Your Motherboard might not be up to date. (revision or bios version)

    First thing to do :
    Unplugg everything (EVERYTHING)
    NO CPU, NO RAM, NO VIDEO CARD, NO NOTHING.
    Take you MOBO out of you case.
    Install CPU + heatsink.
    From there...IMPORTANT don't go further.
    Read your mobo guide, and follow instruction to FLASH BIOS
    (Usually you do have to change the jumper position for 10 sec.)

    Then .
    Install RAM and VDO card.

    NO HARD DRIVER, CDROM, FLOPPY
    Plugg the POWERSWITCH and SPEAKER only.

    Try to boot. If you get any BEEP....problem solve.
    If not...keep searching

    um, how can you flash a BIOS without a CPU or RAM---- can't be done.

    Also, with no hard drive, cdrom, or floppy, how is it possible to get a new bios on there??? Telepathy???

    First the CPU must be in when you flash the BIOS

    Secondo the BIOS is not located on your hard drive neither your RAM. But you'll need your RAM to access the BIOS. but to flash the bios you do need to get in your BIOS.
    So the BIOS is on you Motherboard. That's one reason why you have a battery on your MOBO to keep that information.

    (Usually to flash the bios. Unplugg everything. Keep only CPU, take the battery out, put the battery back, move the jumper (the CLEAR CMOS one) for 10 sec. then but it back to it's original place.)

    So juste read your manual...it's written in there.
    NO RAM-NO HDD-NO CDROM-NO FLOPPY

    After that, plugg back everything, then it should boot, at least give you BEEPS....

    resp. to RIK

    by the way RIK, I didn't say UPDATE OR CHANGE your BIOS....I've said FLASH bios.

    And I don't think telepaty works with computer...

    MrNoname, what you are describing is clearing the cmos, not flashing the bios.
    Clearig the cmos means to clear out all previously saved settings.
    Flashing the bios means replacing the existing bios with a different version.

    These are 2 very different things!!!!!!!!!!!!!!
