    Random BSOD's at random moments


    Hi,

    I'm new here, but I have a BSOD issue. I use Windows 7 Home Premium, but since i got the pc from a friend, I've been having BSOD issuses. I tried updating my graphics card, but this had no effect. Also, I swapped my RAM cards in different orders, but this works for only a couple of days. I have no idea what is causing all this. I attached the log file. Someone with any idea?

    Thanks a lot in advance.

    This looks like malware, more specifically a rootkit.

    Code:
    BugCheck 1000008E, {80000004, 82e5a608, a464f870, 0}
    Code:

    The rootkit appears to be using Direct Kernel Object Manipulation and hiding to prevent detection.

    I would use Kaspersky's TDSSKiller Anti Rootkit utility to find the virus(s)

    I would give Avast MBR a try then we'll go from there.

    aswMBR Download

    Run Windows Security Essentials as well.

    I ran aswMBR but nothing was found, as far as i can see. I attached the log file. I did a recovery on windows lately, but that didnt help. Also, as mentioned before, I tried to switch between RAM slots. This worked out the first time, but after about a month or two, it started all over again... any ideas left? Thanks a lot already though.

    The rest of your dump files are very random, you've got 0xD1 bugchecks.

    Code:
    BugCheck D1, {0, 2, 1, 8b9c743f}
    A null referenced pointer at an IRQL too high with a write operation, this is normally caused by drivers but given the situation I feel bad RAM is the cause.
    To add to this there is nothing in the raw stack at all which isn't good at all.

       Information

    Download it here:

    Memtest86+ - Advanced Memory Diagnostic Tool

    Which one should I download?

    You have two options to choose from, you can either download the ISO version then burn it do a CD and boot it from there.
    The other option is downloading the auto installer for USB sticks, you then boot from that USB stick.
    Be warned though, it will format your USB then install the files needed to make it bootable so any files left over will be wiped off.

    So how does it work?

    It works by writing a series of test patterns to most memory addresses over 9 tests, it then reads the data back to compare it for errors.

    The default pass does 9 different tests varying in access patterns and test data. A tenth pass is optional from the menu which writes all the memory in zeroes then sleeps for 90 minutes and compares it to see if any address have changed, this takes 3 hours per pass each time.

    My memtest86 isn't booting! What should I do?

    This can be caused by a number of different reasons, common ones include your BIOS not setting using the correct settings, you might want to change your boot priority order.
    Other causes include your motherboard not supporting bootable USB sticks in which case you'll need to use a CD (or floppy drive).

    Any other issues you might want to look here:

    Sorry for the late reply , been really busy these days.

    I ran memtest, but it didnt find a single fault... ANY idea what else could cause all these different BSoD's?

    Let us know how many passes you ran memtest86+.

    Also upload your MSINFO32.nfo file.

    1. Click on the start button
    2. Type "msinfo32" (without quotes) in the search bar of the start menu, click the resulting link. It will open the System Information window.
    3. File>Save. In the "File Name" filed, put "MSINFO32" (without Quote), give the save location to desktop, and click the "save" button.
    4. Give the time for processing, it will save a .nfo file on your desktop.
    5. Zip it, and upload it following the instruction.

    Hmm I only ran it once, I stopped it while working on the second test... I'll run it for the next 3 hours. Also I attached the file.
    Thanks a lot !

    Do two things.

    First, open the computer. Apply the SATA cable on a different port on the motherboard.

    And complete 8 passes with memtest 86+.

    Let us know the situation after that.
