KR7A-133 - boot v no boot reason?

    I recently enabled (in the BIOS) the option to shut down if the CPU fan
    PC became difficult to start - would power up for about 3 seconds and then
    CMOS reset seemed to be the only thing to work to get it restarted.
    Disabling the option fixed the problem :)
    Now the question - Does this mean that the fan is about to fail - slow to
    start up maybe and being detected by
    the BIOS as too slow (or stopped) ?
    or is it just a BIOS funny ?

    Anybody out there experience this ?

  2. More than likely, it is the tachometer lead of the fan that's faulty. It's
    misreporting the fan speed or reporting a speed of zero.

    I agree with Colon,

    If your CPU cooling fan is indeed spinning, then the tach lead may
    be faulty. Remove and replace the fan lead connector from the MB
    connector several times to clean the MB fan posts. This MAY cure
    your problem. I have had this function enabled since day one and
    never had a problem. Sheesh, mine will probably fail any second,
    now that I said that. LOL

    Thanks guys,

    Fan lead *looks* Ok , but I will get a replacement and try it .

    The remove and replace effort did not solve the problem :(
