*******************************************************************************

KERNEL_MODE_EXCEPTION_NOT_HANDLED_M (1000008e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: 83461b86, The address that the exception occurred at
Arg3: a0ec1bd4, Trap Frame
Arg4: 00000000

The first thing I noticed that Babylon wasn't working anymore after the BSOD, had to reinstall it.
so, what you think guys? it was Babylon fault?

thanks in advance

While the analysis is correct as far as it goes we can examine it in more detail. We need the actual DMP file

If you wish to have others assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder. The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
* Briefly describe the problem history and circumstances in the same post. Somebody will attend to your query as soon as possible.

the minidump file is attached now
