    On Sat 22/04/2017 16:30:15 your computer crashed
    crash dump file: C:\WINDOWS\memory.dmp
    This was probably caused by the following module: Unknown (0xFFFF9C86AA41AB40)
    Bugcheck code: 0xC2 (0x7, 0x0, 0x0, 0xFFFF9C86AA41AB40)
    Error: BAD_POOL_CALLER
    Bug check description: This indicates that the current thread is making a bad pool request.
    This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
    A third party driver was identified as the probable root cause of this system error.

    The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.
  3. Try to install driver 17.3.3 (use the guide on this forum to delete the newer)

    basically you have a bad driver, it freed up a kernel memory address twice,
    the first time it worked, the second time it did not own the memory address so windows called a bugcheck.

    pool is just memory areas shared by device drivers. if a device driver frees up a memory block, then the windows memory manager gives the block to another driver. If the first driver frees up the memory a second time, it causes the other driver to crash.

    you would have to provide the actual memory dump files from c:\windows\minidump. Ie put them on a cloud service like microsoft one drive, share the files for public access and post a link.

    generally, you would fix this by going to the motherboard vendors website and updating the motherboard drivers to the current version.
    These are the only drivers that windows update does not provide.

    sometimes you will have to turn on debugging flags to find the name of the bad driver. (verifier.exe)
