    BSOD error 0x0000007f


    Hi, I've been getting BSODs for the past couple of months. I'm running Windows 7 Professional x64 on a one-year-old Sony Vaio VPCS12C7E laptop. It's the original OS which came installed on the system, and I've never re-installed it.

    The BSODs all share some basic features:


    • They're all 0x0000007f UNEXPECTED_KERNEL_MODE_TRAP errors (see attached dump files).
    • They all happen when watching content online (usually Adobe Flash based, such as YouTube) though occasionally offline when using VLC player.
    • They all happen seemingly sporadicly - either thirty seconds or two hours under the above conditions.

    The BSODs also occur more instantaneously when streaming high-quality videos or multiple files at once.

    They started happening directly after I inserted an empty USB memory stick from a friend into my laptop. I can't recall the make or model of the USB stick off the top of my head, but it might have been the cause or simply a coincidence - I've not been able to get my head around it.

    Anyway, here are the dump files - thank you so much for your efforts.

    Pull out useless USB-devices from your machine also.

    Also upload any incoming new .dmp.

    Hi Frederik, thanks so much. I've taken a screenshot - though there's nothing useless plugged in at the moment and no crashes today thankfully.
