    Hi

    I've an older homebuilt machine here that has started behaving oddly
    on boot up

    I will get a message saying that CPU frequency has changed and to
    enter the BIOS to confirm settings. I do this and confirm and save and
    then get the error again.

    I suspect this is a BIOS or mobo issue as memory frequency is often
    misreported as 100mhz when it should be 133mhz. Sometimes though the
    machine boots fine.

    On occasion the thing will simply shut off, and the only way to get it
    to reboot is to unplug it from the mains and try again after a few
    hours.

    Fans are all working fine, and I've replaced the mobo BIOS battery.

    Is this a write off and time to buy a new mobo/processor and memory?

    Any advice welcome,

    TIA

    Andrew

  2. What MoBo? I've seen this sort of behavior with the odd 810MLR board
    (PC Chips).

  6. Ah yes I should hve said originally, Its an Epox 8RDA+ with 1Gb RAM in
    2x512Mb sticks with an AMD Athlon 2600 processor. The processor will
    also misreported on occasion as an Athlon 1200, though I think this is
    linked to when the FSB is misread as 100Mhz instead of 166Mhz

  7. Bitstring <>, from the
    Many of those boards (all?), mine included, had dodgy caps and exhibited
    all sorts of random faults. Check for capacitor leaks and bulges. Then
    check again. Nice boards, shame about the quality ...

  8. Mine too. I replaced two whole sets of caps on my 8RDA3+.

    It's still going strong. Needs another set of caps though... I
    shouldn't have recycled them off similar age boards!
