    BSOD when waking up from sleep


    My computer fails about 1/4 of the time when waking up from standby (sleep). I've attached all the necessary files. Any help will be greatly appreciated.

    Welcome
    Your minidump files have been examined. They indicate that a Microsoft driver is the culprit and this is very unlikely.
    To start make a full antivirus scan, download and make a full scan with malwarebytes, and finally try to go to sleep whil not in the power save mode. Report back with the results.
    If you continue to have BSODs, we will suggest other action, such as a driver verifier. We will get this problem resolved.

    Thank you richc46 for your reply appreciated.

    I scanned my computer with Avast boot scan, and with malwarebytes both are clean (logs attached). I set my the power options to high performance, and reset it to default. It still crashes when returning from sleep (though only about one in six times), just a slightly different message (message and dumps are attached).

    Again, the dump gave a driver as the culprit, but once again, it was a Microsoft Driver. Lets see if it is actually a driver causing the problem. Lets try the Driver Verifier:

    Driver Verifier
    I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Windows 7 Startup Repair feature).

    In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

    Then, here's the procedure:
    - Go to Start and type in "verifier" (without the quotes) and press Enter
    - Select "Create custom settings (for code developers)" and click "Next"
    - Select "Select individual settings from a full list" and click "Next"
    - Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
    - Select "Select driver names from a list" and click "Next"
    Then select all drivers NOT provided by Microsoft and click "Next"
    - Select "Finish" on the next page.

    Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because
    Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

    If you can't get into Windows because it crashes too soon, try it in Safe Mode.
    If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

    Thanks again for your time,

    I've done as you described, and the computer failed while windows was loading. Going into safe mode and disabling the verifier got things back in order. Attached is the dump and photo of error.

    This seems to be the cause of your problem. Make a system restore point, first. Then delete the software and test
    BazisVirtualCDBus.sys,

    I wasn't sure how and what you wanted me to uninstall but googleing BazisVirtualCDBus.sys showed that it belongs to Wincdemu. So I uninstalled it, but I still got BSOD after sleeping, so a quick search in C: showed that this file is still larking around (photo attached). So I deleted it manually from system32 folder from cmd (using cacls and takeown command) and searched through the registry and deleted any keys containing BazisVirtualCDBus.sys string. (I'm sorry if I wasn't supposed to do this, I can restore my system to the previous state if necessary, I just wasn't sure how I'm supposed to get rid of the file.) Anyhow I restarted and my computer works great as usual until I put it to sleep then it I get BSOD every single time it goes to sleep, dump attached.

    Take your computer out of power save mode. You can start by going to control panel>power options. Set it for high performance and then report back.

    Edit: If that does not work try with a clean boot and report back.

    One more detail that I've noticed, the computer crashes only when going to sleep by itself, if I press the power button causing it to sleep it wakes up without any problems.
