Welcome,

I have analyzed your dmp files. The probable cause is wireless drivers or modem drivers. Update them or just uninstall and install the most current from the manufacturers website.

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
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: 825c6703, The address that the exception occurred at
Arg3: 8cde5ba8, Exception Record Address

Well that explains a lot. This only started happening after I plugged in a mobile modem for a while yesterday. The blue screen never came up when I worked off of our house modem back home.

Hi! - i know that has been a while since you wrote this, I have had the same problem.

May i ask if you used some kind of usb extension cable to the modem?

Direct USB or via USB hub?

Hi, I have also experienced this problem using a Huawei 1820 USB 3G modem. I have been using the modem for months but only had this problem after I connected it to an i-rocks IR-1406 powered USB hub.

I was also interested if the modem was connected to a USB extension or hub?

Nope, it plugs directly into the USB port though it did come with a USB Extension Cable. And it's a Huawei model too.

On another note, more blue screens have been appearing -

Copy of mini-dump attached.
This time I wasn't using the mobile modem at all, which leads me to suspect something else could be awry with my system.

I doubt that this caused by vegas90.exe, product Vegas Pro, Sony corporation.

Code:
BugCheck 4E, {99, 2924c, 5, 1}

Probably caused by : memory_corruption ( nt!MiBadShareCount+24 )

Mmm. Interesting, because seconds beforehand I had just saved a project I was working on in the program when it bluescreen'd.

Have you ever checked your RAM?
Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Boot from the CD, and leave it running for at least 5 or 6 passes.

You can also enable Driver Verifier to identify bad drivers:

A couple of months back, I got 2GB of extra RAM installed, but only 1GB of that additional RAM is usable.
