  1. Hello,

    i get a lot of bluescreens under Windows 7

    I allready had

    BAD_POOL_HEADER
    and
    IRQL_NOT_LESS_OR_EQUAL

    As attatchment, some minidumps

    On this same pc i've also had bluescreens under windows XP (allways when I used sonicstage) but had never problems in linux.

    Could someone help me?

    EDIT: I've ran a memtest and had no errors

    All minidump errors are 0x00000019: BAD_POOL_HEADER

    A pool header issue is a problem with Windows memory allocation. Device driver issues are probably the msot common, but this can have diverse causes including bad sectors or other disk write issues, and problems with some routers.

    All dumps cite the same Windows OS driver classpnp.sys. Normally OS drivers are too general to be of much help.

    However, this one can lead us to some diagnostic steps This OS driver is for SCSI (Small Computer System Interface) peripherals and is most common for harddrives but also forCD/DVD drives, etc.

    1. Do a harddrive diagnostics. Your HD manufacturer should supply a free utility in order to do so off their website. Do both short and long tests.

    2. Update your controller drivers.

    I've just realised something, I'm using ext2fsd to acces my ext3 partition. Could this be the cause?

    I've removed the ext2fsd driver, i think the problem is solved, I'm not sure yet but so far had no bluescreens

    Thanks for getting back to us. Keep us up-to-date if you continue to have (or not) stability.

    It seems like they're really gone. Ext2fsd caused the bluescreens.
