    Crash with no logs?


    Here is my situation. I had a Windows 7 machine that ran for about 2 years with 0 problems. It pretty much only rebooted when Windows Update forced an update. About a month ago, I updated the MB BIOS and upgraded the CPU FAN to a Cool Master Hyper 212. About a week later, my Windows 7 machine started crashing every day or two. There were no BSODs, no crashdump files, and nothing in the Event viewer other than the critical kernel restart error (after the system came back up after the reload).

    I then disabled restart on error and found the crashes turned into a frozen computer that was completely unresponsive. Network stack was down (didn't respond to pings), mouse/keyboard was unresponsive, etc. The only thing that I saw was a frozen screen still showing Windows 7 desktop.

    I then figured now was as a good of time as any to upgrade to Windows 10 to see if that helped. I upgraded to Windows 10, which failed and rendered my drive unbootable . I then did a clean install of Windows 10 and got back up and running. About a day later, I started getting the same crashes with no crashlog, no event log, no BSOD, etc. I then disabled restart on error and saw the same thing as I saw in Windows 7.


    Hmmmm. I didn't think it was HW as nothing really changed. Could a BIOS UPGRADE cause this? I didn't think so. So, I loaded up Ubuntu linux (booted from a USB drive) and let that run for a while. Ubuntu has been up for 5 days with no problems. Hmmmm, let's see what happens when I run a Windows 7 and Windows 10 VM on Ubuntu. I booted up a Windows 7 and Windows 10 VM (storage was NFS mounted from somewhere else). After about 24-48 hours, both Windows 7 and Windows 10 VMs were crashing in the same way. Ubuntu showed 0 errors in syslog, kernlog, or dmesg.

    Any idea on what would cause this? I'm thinking something the HW is doing is causing Windows to crash but I'm not sure it's an actual hardware error since Ubuntu is not reporting any events.

    Edit: I also ran the Ubuntu mem check with no problems and ran "stress" on the CPU for about 5 hours with no issues.

    Edit: The Windows 7 VM crashes did produce some minidump crash logs. They are attached.

    Edit: Here is the dump from the main system.

    The dumps from VM are pointing to memory, but that isn't really helpful because it could be entirely different for the main system.

    What I would need to have is collected files from the main system.

    When you talk about crashes, what kind of crashes exactly are you talking about?
    1. Freeze crashes,
    2. Bluescreen crashes,
    3. Shutdown/restart crashes.

    A lot think that all of them create dump files, but only a bluescreen creates a dump file because with a freeze crash the system can't respond and with a shutdown/restart crash there isn't time for it.

    Just attached the dumps from the main system. It "freeze crashes" if I disable Control Panel -> System and Security -> System -> System Properties -> Startup and Recovery -> Automatically restart and restart crashes when that setting is enabled. What I mean is that when it freeze crashes, the system will sit for hours/days showing a frozen screen (displaying the time of the crash), mouse/keyboard don't work, device i not pingable, nothing really works except the monitor. The only way to recover is to pull the power.

    That is what I thought, freeze crashes are very different from bluescreen crashes.

    We'll need to know if this is persistent in safe mode, if so then you have most likely somewhere a bad component.
    Try booting in safe mode and see if the problem still persist.

    OK, I'll try putting it into safe mode for the weekend. Wouldn't the system running Ubuntu for 5 days straight with no problems be equivalent to safe mode though for this test?

    If the computer runs Ubuntu without problem that is a good indication, but not a conclusive one, that the problem is software related. Safe Mode uses a minimal set of drivers and services. Running in Safe Mode helps to isolate the problem, is it in the minimal set of drivers and services or something else.

    axe0 knows more about this than I do.
