    How do I create a crash dump in the first place?


    I thought installing debugging tools would initiate a crash dump, but after I crashed I couldn't find a *.dmp file on my system anywhere. Do I have to initiate this process somewhere else, and if so where? This may seem obvious to you guys, but it's totally opaque to me.

    Perhaps its there, but just hidden from you. Have you enabled the "show hidden files" function?

    No, there just aren't any. Again, how do you *initiate* the logging of *.dmp files. That seems like step 1, so if that's omitted from the tutorial the debugger tools aren't much use.

    Click on "Start"
    Open "Control Panel"
    Open "System & Security"
    Click on "System"
    Click on "Advanced system settings" (on the left side of the window)
    This will open the Systems Properties box.
    Click on the "Advanced" tab.
    Click on the "Settings" button in the Setup and recovery section.
    Tic the box "Write an event to the system log"
    Choose the type of dump you want (Kernal or Small)
    Decide if you want to overwrite the existing dumps or keep the old and the new
    "OK" your way back out

    Edit: This is usually not necessary as Win7 usually installs with the correct boxes checked, but sometimes it doesn't... dunno why. Happy bug hunting!

    These were already checked, and it's supposedly saving a log file with the extension *.dmp, but I couldn't find it. Where would it be located? I suspect it's in one of those folders I don't have access too, even as administrator, unless I ask for it. (This is an irritating aspect of Windows 7.)

    Well, we've reached the end of my knowledge. If the system is set to save a minidump, and you're allowed to see the hidden files and folders, then you should be able to see the minidump files. Unless your system is crashing without blue screening, then no minidumps are created.

    Start a new thread in this subforum and ask for more help... someone far more knowledgeable will be glad to help. Sorry!

    Thanks. Actually it was set to save a kernel dump and I changed it to minidump, but I still should have been able to see the kernel dump, right? Yes, there aren't any blue screens... it just freezes. I just did a clean install on another disk and then used Easy Transfer, so I'm in the middle of re-installing all my software. Hopefully I won't be crashing after that, unless it's a hardware problem. I suspect the issue was that I was running windows on a dynamic disk, which also had a basic partition on the same disk that couldn't be altered. It's wierd, and I still haven't fixed it, but now at least my system isn't on that crazy dynamic disk.

    OK, if it just freezes and doesn't give you a classic BSOD, then there won't be a minidump. You could check in the Event Viewer (enter "event viewer" in search) for error messages, sometimes the problem will show up in one of the categories in there. But with any luck, the reinstall will fix the problem. Freezes are notoriously hard to diagnose... they could be anything from antivirus vs. firewall conflicts to driver issues to hardware problems like a dying/inadequate power supply... and many more. Hope the reinstall works!

    No such luck. Still freezes. The time freezes too, so when I reboot I'll check the event viewer around that time to see what happened. (Clock is stuck on 3:49PM.) It's definitely *not* the power supply, because I've swapped out a couple of them to no effect. I have a KVM switch that I've been using, but it has never done this before. And I'm currently submitting this from my MacBook as my Win7 box is frozen, so I'm not sure why half the KVM switch would be working. Plus, plugging in other mice and keyboards don't help the matter. I wish there was some way to recover from this other than a hard reboot. Those are really hard on the system, especially when they happen about once a day.
