A question before I replace a motherboard

    A co-worker had a friend try to fix a problem with his two year old
    Systemax WinXP system that was freezing at mostly random times. Except
    for drinking all his beer he accomplished little. It came to me. I booted
    it up and sure enough it would freeze while downloading patches or even
    while doing nothing. Swapped out the DDRAM with known good ones of the
    right type. No good. CPU fan was working fine, so I pulled the HeatSink
    and reseated it with good thermal compound. Still freezing. Tried to do a
    system restore using the Systemax included software. It frooze at 98%.
    Temporarily installed another hard drive, but had the same problem, so it
    wasn't the operating system causing it. Has to be hardware related.
    Swapped the 300Watt power supply for a 450Watt with no luck there either.
    The motherboard, a BIOSTAR MicroATX U8668D Socket 478 with the VIA
    chipset, has integrated Video and Sound so there were no cards to replace.
    As far as I can see that leaves only one conclusion, the motherboard has
    issues. Any thoughts on this appreciated.

    Good thought, thanks. Yanked the power and IDE cable and I was hopeful at
    first because it ran ok for 30 minutes or so, but then the system locked
    up solid like before. Oh, well. Thanks again.

  4. Try going into the CMOS and disabling the video and sound. Add an AGP card
    you might have lying around (careful of the voltage if the board is fairly
    new) and see how it does. If it does alright, re-enable the sound and see if
    that's still OK. Use a process of elimination. I'm no expert... but I'd
    eliminate these before buying another board. You could get a video card that
    might be faster than the on-board for cheeper than a board using Pricewatch.
    Use a test card first... you could even try an old PCI video, but not with
    any fast apps unless you are sure the PCI card can handle it without giving
    you another, misleading error.

    Damn. Just when I think I've exhausted every option someone points out an
    embarrassingly obvious possibility. I do have several cards laying around
    that I can try. Thanks. Back to work I go.

    I had a similar problem recently.I tried swapping out everything until the
    last thing I tried,which was the CPU,and since then it has been fine

    No luck. Tried two separate AGP cards after disabling video and sound
    with the same results. Random freezes. Thanks again.

    This really frosts me. That flimsy plastic bracket they bolt to the
    motherboard for the Socket 478 Heatsink/Fan had a crack at the bottom
    right side where the clip secures it. The Heatsink wasn't sitting on the
    CPU properly as a result and was overheating. The BIOS was showing a Temp
    of 60C while idle, which is high for a P4 2.2G, but the HS fan was working
    so I wrote it off as a crappy Heatsink/Fan combo. That is until the part
    came loose completely and the bottom Heat Sink clamp fell off. Replaced
    the bracket and all is working fine. I've been testing it for two days
    now and it appears the CPU didn't suffer any noticeable damage from
    overheating. Just thought I'd pass this along for future reference. Thanks
    to all who replied.
