    I have a Lexa Blackline case with Abit fp-in9 mobo.

    The boards runs fine when setup outside the case on just some card but when inserted in the case it freezes within 10 secs, sometimes in bios and sometimes just at xp login.

    It must be a shorting issue.

    I have tried the following thoroughly:

    >insert mobo with no screws

    >insert mobo with washers over the stand offs

    >put a static bag under the mobo when in the case

    >put risers in to lift up mobo so it is not touching off back plate

    >Set up hdd and psu outside the case while mobo is in case

    >tried all hardware on another mobo in the same Lexa case and it works so it must be the actual mobo shorting somewhere

    As i have said the board runs ine when set up outside the case with no shorting or anything.

    Its only when placed inside the case that the shorting happens.

    How annoying this is:(

    I expect you have tried this,but could the problem be the fact that the motherboard is vertical when in case but you may be testing it outside of the case with it lying down ,if this is the case it may be perhaps something like the fan is jamming when placed vertically.
    just a thought !!!

    Motherboards are polarized. If you plug in the power on switch plug backwards, it will short.
