    windows 8 bsod ntoskrnl.exe+7a040


    Hi all,
    This is my first post here, so greeting to you folks.
    Anyway, my problem is that I recently installed Windows 8 Pro on my Acer Aspire One netbook 722 with AMD processor.
    And I got a BSOD today. I uploaded my dmp file to mediafire 021613-24913-01.dmp
    I have no idea how to proceed further, or what could be wrong. I simply used this tool Blue screen of death (STOP error) information in dump files. to view the dmp file and figured it had something to do with ntoskrnl.exe
    Please help, this is my primary on-the-go computer and I cant afford it BSOD-ing on me again.

    Thanks and regards.

    Edit: I am attaching the zipped files here too.

    It happened again. I rebooted my laptop, and the first thing I did was open Firefox and started typing a URL, and boom! the computer crashed again.
    I tried doing the same thing again. rebooted, opened firefox and typed a URL and another BSOD.
    could firefox be causing this? I have not heard of firefox causing any BSODs. but then again, when I rebooted, I instead opened IE10, and it seems to be working fine as I type this.

    attaching new dump file.

    EDIT: I have run both sfc /scannow and chkdsk in elevated command prompts. both came clean with no errors.

    Hi and welcome to the forum. The mini-dumps you have supplied don't seem to be pointing to any driver in particular. Normally I would advise updating or removing out-of-date drivers on your system but in your case I can't find any.

    The one thing I did notice is your BIOS seems to be out-of-date, your BIOS version is v1.06 (2011) and the latest on your manufacturers website is v1.11. Please be aware if you decide to update follow all manufacturers instructions otherwise you might find your system in-operable:

    Acer Support: Downloads & Support Documents - Netbook, Chromebook / Aspire One / AO722 (click on BIOS)

    If this does not help I recommend doing a memory and hard-drive diagnostic check in-case this is a hardware problem. Please follow the articles on this site for doing this:

    Hard Drive Diagnostic Procedure

    Thank you for your response. The drivers should be up-to-date, as I downloaded them from Acer's website just weeks ago, when I installed Windows 8. I will run the diagnostics and report back.
    As for the BIOS update, I am very hesitant to do so because of the numerous horror stories I have heard about systems getting bricked. but if the diagnostics don't report anything, then perhaps I will go ahead and do the bios update.

    I ran the memtest86+ and the hd utility. both reported no problems. so i upgraded the BIOS to version 1.11 as you recommended.
    And then i rebooted the machine and ran firefox and used it for a bit. i am happy to say so far it has not BSOD-ed! let's see if this holds up/ how long it holds up for.
    Thank you so far. Will keep you posted.

    I spoke too soon. it just crashed on me three times in succession.
    the first when I was on firefox and ebay. the second time I literally just clicked the firefox icon to start after reboot.
    the third time when I open IE 10! I am honestly stumped at this point. I have upgraded the BIOS and ran all the checks above, and yet this happens.
    Any ideas/ suggestions?
    thanks once again.

    These dumps all point to win32k crashing during the closing of a window or the destruction of data contained within a window (and considering IE10 is accelerated, this isn't totally odd for IE anymore either):

    Something running on the machine is causing issues here - as previously recommended, I'd recommend making sure your BIOS is the latest version, but also I would recommend upgrading to the latest version of the ATI suite for your video card/chipset directly from AMD/ATI. If, after updating your drivers and the BIOS (assuming there's a BIOS update), the problem continues, you'll need to configure your system for a *complete* memory dump - mini or kernel dumps may not be enough if a driver update doesn't fix it. However, given this is video work, the best place to start is the video driver and the system BIOS.

    Thank you for your more in-depth response. As I mentioned earlier, I already updated the BIOS to v1.11 which is the latest from Acers website. As for the AMD graphics drivers, I think there has not been a version released after the already installed version. In fact, I cannot seem to find the driver for Windows 8 elsewhere, except on Acer's driver downloads page. Perhaps, Acer thinks the driver works for Windows 8, but ATI itself is not so sure. If you could find the driver for it elsewhere please post here.
    AMD Catalyst Here it asks you to contact your vendor, and the vendor's driver is the one i have.

    The weird thing is that the laptop was working fine for a couple of weeks and then it suddenly started BSOD-ing. Also on the forum, it seems i am not the only one with this problem.
    BSOD opening different browsers this person posted something eerily similar. And the person here Random Windows 8 BSODs Started Today has my same model netbook, and their crashes also started recently, although their problem had to do with different sets of drivers.

    Try using AMD's "Auto-detect" program here, it should update your drivers:

    Thank you for that link. It says cant recognize your OS or graphics card. Which is extremely strange.

    At this point I am ready to dump this Windows 8 crap, and revert back to the tried and tested Windows 7, with all software I use working, and there seems to be no problem with drivers, hardware etc. Not once did have a BSOD with Windows 7 on this laptop.

    So unless there seems to be another solution to this, I can't afford to waste my time on 'fixing' brand new Windows 8 installs. Especially since the weekend is over. So I will wait till you folks say you have no idea either, and then in that case revert back to Windows 7.
