Windows XP BSODs Helps

  1. Hello,

    Please could someone have a look through the attached minidumps and offer some advice as what the problem is - as I have been having BSODs regularly for the past year.

    I have done all the usual checks including updating drivers, reinstalling windows, memtest for 12 hours, disk check etc but found nothing. The crash checks from windows report that the BSOD was caused by a driver. But then list that it could equally be a hardware problem!

    I wonder if it might be either a problem with the McAlfee Virus scanner/ firewall (as a driver is not certified by XP) or the Sapphire PCI-E video card. I have heard that these early PCI-E cards are unstable due to insufficient power supply via the motherboard and the new cards a powered externally.

    I would be grateful if you could find any clues in the attached minidumps...

    Thanks in advance

    The culprit is faulty memory. You can run memtest to stress the ram. If memtest reports the ram is faulty, ram is bad. However Memtest is not a perfect tool to test the memory as some faulty ram can pass memtest.

    1. Check the temperature of the CPU and make sure that it is not overheat (ie temperature < 60C)
    Make sure that the CPU fan works properly
    2. Reseat the memory stick to another memory slot. Reseat video card as well.
    3. Downclock the ram. Check to default setting if you video card is overclocked.
    4. Clean the dust inside the computer case
    5. Make sure that the ram is compatible to the motherboard
    6. Check the bios setting about memory timing and make sure that it is on
    For example : DIMM1 and DIMM2 do not have the same timing.
    DIMM1: Corsair CMX512-3200C2 512 MB PC3200 DDR SDRAM (2.5-3-3-8 @ 200 MHz) (2.0-3-3-7 @ 166 MHz)
    DIMM2: Corsair CMX512-3200C2 512 MB PC3200 DDR SDRAM (3.0-3-3-8 @ 200 MHz)
    DIMM3: Corsair CMX512-3200C2 512 MB PC3200 DDR SDRAM (3.0-3-3-8 @ 200 MHz)
    7. Make sure that your PSU have adequate power to drive all the hardware including USB devices

    If it still crashes, diagnostic which memory stick is faulty
    1. Take out one memory stick. If windows does not crash, the removed memory stick is faulty.
    2. If you have only one memory stick, replace the ram
