    Blue Screen of Death message

    When I started Win 7 yesterday I was called away just as I pressed the power button. When I returned I saw a message regarding a BSOD. The Blue Screen View file reads as follows, and if someone can interpret this for me and tell me what I can do about it I would be grateful:

    Hi, Roy.

    That txt file is of little use, better to zip and upload the minidump itself (C:\Windows\Minidump, unhide files and folders to see them).

    A much better plan would be to carefully read and follow the instructions here, attaching the resulting zipped folder will give us much more data to work from.

    What I do is restore a previous registry (provided the BSOD doesn't repeat immediately) and then see if the BSOD repeats or not. One needs one or more repeats of a BSOD to be sure it's a problem.

    satrow, thanks. The minidump file is attached, and if this is not sufficient I will follow the instructions in your link.

    Please advise further.

    Roy, this feels like it might be a one-off, maybe some fluke of timing where a Windows standard post boot security check stumbles against a 3rd party scheduled scan/backup.

    BugCheck 1000007E, {ffffffffc0000005, fffff8800928e161, fffff8800337e3f8, fffff8800337dc50}

    Run SFC /scannow and if it reports errors that it couldn't fix, reboot and run it again - and reboot and run it a third time if that one still reports errors.

    If you can carefully follow the Sysnative topic (running the app. as Administrator is imperative for Autoruns to verify files) and upload the resulting zipped folder, I might be able to pinpoint a likely trigger for this; if so, there may be a method to simply delay that scan/backup/whatever, or to find a less intrusive/more controllable equivalent to use.

    Attachment 38998Windows7_Vista_jcgriff2.zip[satrow, thanks again. The 2 files mentioned in the Sysnative topic (Jims BSOD) are attached.

    sfc /scannow did not report any errors, and I do not run any scheduled scans or backups.

    Regarding the perfmon report saying no antivirus program was detected, I do have avast internet security running, and it is always on, but for some reason Windows doesn't recognize it.

    The BSOD has not recurred.

    Please advise further.

    Regards,
    Roy

    satrow, regarding my previous post, I tried 3 times to upload perfmon.zip, and did in fact do so, but as you will see when you try to open it it is said to be invalid, and i don't know why.

    Help!

    Regards,
    Roy

    Hi, Roy.

    I'm currently having some problems, I've asked for some help with your BSOD problem, hopefully you'll get further instructions soon.

    I agree with satrow.

    If the BSODs are in fact being caused by software, Driver Verifier should be able to help us ID a 3rd party problematic driver.

    Please run - http://www.sysnative.com/forums/bsod...ows-vista.html

    Would be a good move to test your RAM, but would be a good idea to clean the RAM contacts first (rub gently with a white pencil rubber until the gold contacts look nice and bright/shiny, brush off particles w/ a clean, dry toothbrush (or similar).

    http://www.memtest86.com/

    I am not saying that RAM errors are causing the BSODs, but this is something that is best done at least every 12months or so in any case.

    jcgriff2, thanks. I followed the instructions given in your link and Driver Verifier has been running for about 9 hours now. When I enter the command verifier /query I am told no drivers are currently verified, but when I enter the command verifier /querysettings the settings are listed followed by a list of verified drivers. Is this normal?

    Please advise.

    Thanks and regards, ROY

    jcgriff2, verifier has been running now for about 28 hours, with no change in the command prompt messages. Any comments?

    Hi Roy, if verifier /querysettings lists the drivers, I think it should be working correctly, just keep using the PC as normal, maybe harder, throw in a few more reboots than you normally would.

    DV will add some stress to Windows and the drivers, trying to force another crash and a verified BSOD dump (these are much more useful for troubleshooting); the harder you can work it, the higher the chances are that it will pick up a faulting driver early on.

    There's little point running it for longer than 48 hours, it will only increase the likelihood of a false positive and add unnecessary drag on the PC. If, after ~48 hours the PC hasn't crashed, the chances are very high that the BSOD was unrelated to a driver - time to look elsewhere; some crashes are one-offs, others may only occur sporadically, maybe 6+ weeks apart, they can be tricky to pin down.

    Yes, it'll continue to grind away until you turn it off (verifier /reset and then reboot).
