    locking up/freezing up


    Hi,
    Been having a problem of freezing up for a while and when it does, only way to switch off is flick power point switch.
    I don't think it is software as sometimes it freezes up as soon as I push start button (before win xp pro is initialized)
    My guess is that it is possible CPU or motherboard or both ??
    Running XP pro, sp2, 768 mb ram, 2 x 40mb hard drives
    Any help/hints would be very much appreciated, many thanks in anticipation.
    fjord.

    When you boot up, does it pass POST before freezing? If so, we're probably looking at a software problem, though it's hard to say at this point.

    I'll second that. Sounds like you have some messed up system files. Do you have an older computer? Have you run a virus scan and spyware scan?

    Another possibility


    The heatsink on your CPU may be dirty. I had a box that I was given because it was 'broken'. Cleaned the CPU heatsink and it stopped locking up. If it's overclocked, turn the speed back down too. CPUs lock up when they get too hot.

    Check all your connections also. Maybe that's causing some problems..

    RAM I would expect to be a problem every tme at boot, if the error in RAM is in an area that is used quickly, i.e. is always filled with OS stuff when booting. But I suppose this isn't necessarily the case, I couldn't say for sure.

    Connections I also would guess wouldn't be so intermittent and unpredictable, but it's worth a shot.


    Cleaning the HSF... that's interesting. I suppose heat build-up could be an issue, but that usually results in a reboot.




    Meh... can't do much till he replies back.
