BSOD error 0x0000007f

[woopington]

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.

Carry on.

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.
