BSOD for months now

  1. Hello everyone,

    I'm new here. I'm struggling with BSOD for months now. Tried to figure it out by myself but right now I 'm stuck. I hope I'll find a solution here.

    I included a system overview.

    Also you will find the last memory dumps (the last one is a kernel dump)

    Most of my drivers are up to date, bios too.

    I did some analyzes of the dumps and as a result I sometimes have ohci1394.sys, sometimes it's another file/driver.

    I ran Memtest86+ too, 36 passes, no single error.

    Also, I tried another psu, but nothing...

    If someone can figure something out...

    I think I found the solution.

    Seems Automatic CAS settings in bios were causing the bsod's.
    No more crashes for 2 days (knowing I had at least 2-3 crashes a day)

    My problem was not related to the motherboard. The automatic SPD settings for RAM in the bios didn't work well with my ram. I use the recommended constructor settings now and I had no single BSOD since then :)


    Ok, said hooray too early. Sigh...

    Had another bsod. Frequency seems to be less than before the bios tweak (changed auto spd settings to manual).

    The strange thing is I have no Minidump for this one, altough Windows is configured correctly...
    Just had another bsod.
    I attached the minidump from this bsod.

    Here are also the results of a 150mb memory.dmp from 18/01/2007 I found in c:\windows. If anyone can tell me what is going on ?

    An attempt was made to access a pageable (or completely invalid) address at an
    interrupt request level (IRQL) that is too high. This is usually
    caused by drivers using improper addresses.
    If a kernel debugger is available get the stack backtrace.
