    Memory management, kernal power, system service exception BSOD

    Hello, I am hoping someone can help me with my bluescreen issues. I have been having random bluescreens for a few months, but today I have been getting them over and over again. One of them is a Kernel-power bleuscreen: EventID 41, version 3, level 1, task 63:0x8000000000000002

    I have also gotten memory management errors and one that has been most common is a system service exception bsod. I'm not sure sure if this is relevent to the errors, but I did a sfc /scannow and these are the results: https://drive.google.com/open?id=0B_...0NjcGYxU2dGVGc

    Thank you for your help in advanced.

    Another thing I forgot to add, this kernel power error sometimes just restarts my computer without a bluescreen.

    No crash dumps, so obviously no debugging, but considering you mentioned 0x1A's + random restarts without a bug check being called, I'd check RAM for sure with memtest. 8 passes.


    Download Memtest86+ here:

    Memtest86+ - Advanced Memory Diagnostic Tool

    Which should I download?

    You can either download the pre-compiled .ISO that you would burn to a CD and then boot from the CD, or you can download the auto-installer for the USB key. What this will do is format your USB drive, make it a bootable device, and then install the necessary files. Both do the same job, it's just up to you which you choose, or which you have available (whether it's CD or USB).

    Do note that some older generation motherboards do not support USB-based booting, therefore your only option is CD (or Floppy if you really wanted to).

    How Memtest works (you don't need to read, it's only for those interested in the specifics):

    Memtest uses algorithms (specifically two), namely moving inversion & what is deemed Modulo-X. Essentially, the first algorithm fills the memory with a pattern. Starting at the low address, it checks to see if the pattern was changed (it should not have been), writes the patterns complement, increments the address, and repeats. Starting at the highest address (as opposed to the lowest), it follows the same checklist.

    The reason for the second algorithm is due to a few limitations, with the first being that not all adjacent cells are being tested for interaction due to modern chips being 4 to 16 bits wide regarding data storage. With that said, patterns are used to go ahead and ensure that all adjacent cells have at least been written with all possible one and zero combinations.

    The second is that caching, buffering and out of order execution will interfere with the moving inversions algorithm. However, the second algorithm used is not affected by this. For starting offsets of 0-20, the algorithm will write every 20th location with a pattern, write all other locations with the patterns complement, repeat the previous one (or more) times, and then check every 20th location for the previously mentioned pattern.

    Now that you know how Memtest actually works, it's important to know that the tests it goes through all mean something different. It goes from Test 0 through Test 12, many of which use either one or the other algorithm discussed above, among many other things.

    Any other questions, they can most likely be answered by reading this great guide here:

    Let me know how the memtest goes and then I'll check the dumps.
