    Incorrect, I fear. OpenVPN has been removed, and my current network driver is version 8.1.0.25, dated March 18, 2015. Most of those crash dumps, except for the most recent, occurred before changing drivers. Also, my nVidia driver is current (353.30, dated June 22/2015.) There is nothing more recent.

    Neither MEMTEST86, nor SFC report any problems. I will not use MEMTEST86+, as it's several years out of date, doesn't recognize my RAM (too recent), and can't read my BIOS SPD settings. I'll try MEMTEST86 on individual chips when I have more time, but since it takes a minimum of 5 hours to test one chip, that won't be while I have guests and need this computer for work.

    CHKDSK found some minor problems and cleaned up. I'm not surprised, as random restarts are bound to interrupt file writes.

    TAP-Win32 Adapter V9 device can be removed manually.

    For your network driver there appears to be a workaround MSI Computers workaround.
    Simply disable Qualcomm Atheros Killer Service in msconfig, disable KillerNetManager in taskmanager and reboot.

    Unfortunately I wouldn't know any other solution a.t.m. that could help, I'll do some research about those BSOD's.

    I appreciate your efforts. As I said, OpenVPN was removed, and the system rebooted before that last BSOD. I had the KillerNetManager disabled already, but I'll disable the service too. I just want internet. I don't need some program imagining it can streamline traffic on a network shared by a 10-room hotel. Only the router can do that; not some app running on my gaming rig, LOL.

    btw, I cannot leave OpenVPN off for long. I need it for work, as it's a requirement of our credit card security protocols. It hasn't caused an issue in the 6 years I ran my old PC, so I tend to think it's not causing a problem now. But it can't hurt to check.

    Why do you think OpenVPN is a problem? Is it mentioned in one of the crash logs, or are you simply concerned about the driver's age? I did mention that to PrivateInternetAccess support, and was told they only support v2.2 at this time, and didn't recommend updating the driver separately from their product.

    MemTest results: The first stick passed 6 complete passes in slot 1. Will use this stick for awhile to test stability, then swap in the other stick for testing. So far, it's managed tasks that were crashing my machine (full antivirus scans, 3DMark, etc.) so it's looking good.

    Because OpenVPN is a program that is pretty well known to cause bluescreens.

    Great to see you're making progress, but
    Memtest86 results: I've run Memtest86 three times now. The first run included all tests. The first pass had 0 errors. Pass 2 was OK until the hammer test, during which there were two bursts of errors, numbering 2679. At the time, RAM was set to the default system specs, which are considerably lower than the memory's factory specs.
    With the memtest the only positive result is zero errors.
    This means you have faulty RAM.

    Didn't see that untill now

    PrivateInternetAccess (the client that's running OpenVPN) has never crashed my machine, or the others I use it on.

    As for memory, I've now run MemTest86 multiple times on both chips together and individually. The only time an error was reported was when my BIOS settings were incorrect. Under the XMP settings, there are no errors running 1 chip at a time, and no more system crashes in the past few days.

    Socket #1 and either chip on its own have been rock-solid. Nothing I've thrown at them, including overnight runs of Prime95, stress tests with 3Dmark, etc. are throwing errors or crashing. The next step is test these chips in the sockets I was using before (#2 and #4) as it's quite possible one or both of those has a problem.

    Moving the memory chips to new sockets appears to have solved my stability issues. I'm marking this solved and will open a new case should the need arise. Thanks again for everyone's help.

    Sadly, I was wrong. While stable for the past few days, my computer rebooted twice today without warning, and with no error message. Once while playing a game (Hand of Fate), and once while checking the TV Guide website. Neither produced a crash log, or any boot errors aside from the usual log errors that everyone using a Home Group in Windows 7 and 8 sees.


    • Session "Pku2uLog" failed to start with the following error: 0xC0000035
    • Session "NegoLog" failed to start with the following error: 0xC0000035
    • Session "IDListenLog" failed to start with the following error: 0xC0000035
    • Session "P2PLog" failed to start with the following error: 0xC0000035
    • Session "HomeGroupLog" failed to start with the following error: 0xC0000035


    I'm at a loss, as I have no idea how to proceed. If memory tests aren't reliable, than nothing is. I expect a perfect world, and cannot deal with chaotic results.

    If you have a .dmp file please use the dm log collector.

    I don't, and I was quite clear on that. No error message means no memory dump. I've put in a support ticket with the system manufacturer, as this is entirely their fault.

    Sorry, I have PDD-Nos autism.
    That easily means its not always as clear for me as for others and otherwise.
