AV8 error codes

    Can anyone offer any help with my possibly dead AV8 board?

    When I first turn the PSU on the POST code display shows a 3, closely
    followed by a 0.2.

    When I short the PWR terminals, the CPU fan spins up, and the POST code
    display shows 8.3, then 9.C, followed by a momentary 9.E and finally a 9.F,
    and the CPU fan powers down.

    I've tried it on the bench, in a case, with and without drives attached,
    memory in this slot, memory in another, you name I think I'll have tried it.
    I'm running out of things to fiddle with!

    Can anyone decode the codes? None of them are in the helpfully supplied
    appendix of POST codes in the manual. (See, I must be desperate - I RTFM!)

    Any suggestions appreciated, useful ones even more so.

    Would love to say yes I know, but Ive also seen error codes not listed in
    the manual, somewhat troubling....

    Thanks for the above, but I notice the codes I'm getting are conspiuously
    absent. I've pretty much given up on the damn thing, (which is a shame as
    it was a fine board when it worked), and have ordered an Asrock 939
    Dual-SATA (and returned it for replacement as it refused to post), which has
    a degree of future-proofing built-in.

    Thanks again.

    I know I am many years late to this conversation but my AV8 board is having similar problems, except it won't turn on period - even with shorted PWR terminals. I just get 3 and then 0.2. It gives me this POST code no matter what is installed or not installed in the board; leading me to think it had a corrupt BIOS.
