    old mobo fried, installed new k7mnf-64 mobo.

    when i power it up i get two audible tones, one short one long sonds like a mini ambulance lol. also red light on mobo stays on.

    nothing is plugged in, no cd or hdd or anything, no cables either, cpu fan not turning on.
    I suspect either fan or cpu itself, any insight?

    Is the cpu fan plugged in?

    Does the cpu have an additional plug that goes to the motherboard? If so, is this attached?

    I expect a short against the case, I'd take the board out of the case and try it there, or a power supply issue.

    Thought it was an ASUS from the designation, turns out to be a FIC :eek:.

    It's a motherboard fault from the beeps (so "anything" really).
    Check the manual to see if the red light means anything specific.

    When you say the old motherboard fried, how did you diagnose that?
    Sure it wasn't the power supply or something else?

    no manual came with the darn board. diagnosing it was easy, burnt chips were visible as an elephant at a smurf reunion.

    Any chance of testing the power supply with a meter?

    Do you have 1 ram stick, cpu, and 2 psu plugs, and video plugged in outside of case?
    If you do and psu is good which I doubt, then you have another bad board. Fic can make those 8 days a week!

    tested the power supply with a analog for a quick check on power, power does exist, how much and where exactly I haven't checked yet.

    i had one ram and cpu plugged in only,as video card is built in as I've been told.

    p.s. i do have a multi meter handy.

    I have seen metering those fail too many times. The only real way to know is use a psu you know works I'm afraid.

    Um, I'm not an electrician, but the meter should tell you how much power it's putting out.....
