    Hello all,

    Recently I have been having major trouble with blue screens on Windows XP. The most frequent are...

    And a sort of generic one that traces the fault to win32k.sys

    These usually occur when playing intense 3D games/apps that tend to hog resources, or when there is a high system load.

    I have recently begun to record some specifics to these errors, and if needed, I can post some. I used the Windows Event Viewer to gain some more insight on the subject, and I believe I have a large clue.

    The report is as follows:
    AMLI: ACPI BIOS is attempting to write to an illegal IO port address (0x4d1), which lies in the 0x4d0 - 0x4d1 protected address range. This could lead to system instability. Please contact your system vendor for technical assistance.

    I am unaware of what this really means, so I'm relying on you gurus to help me out. LOL. :confused:

    Help me!!

    Friend of Bill What, me worry?

    Sounds like a display driver problem.

    The symptoms you describe aren't exactly the ones for this solution but you can try it anyway. Try turning off AGP Fast Writes in BIOS.

    Another thing you can try is turning off ACPI support in BIOS. This may however require a reinstall of Windows.

    Thank you for your replies.

    I don't believe that it is linked to display drivers, as I tested many other drivers for my card and have still received the blue screens. Thank you for your help, though.

    If I were to disable AGP Fast Writes in the BIOS, what would be the implications of that?

    Sidenote: I think my card requires an AGP 2.0 compliant slot, though mine is reported to be only 1.00...could this be related?
