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: 9153daef, The address that the exception occurred at
Arg3: 96989c68, Trap Frame
Arg4: 00000000

Since the card is not in use, I might just try disabling it to see whether that affects anything?

Jonathan_King · 24 Aug 2010

Sure, that would be fine.

higgins · 27 Aug 2010

I was starting to think that disabling the realtek card fixed it, but another BSOD. Minidump added.

Seems to be a networking issue.
Install a new driver

Thanks for stepping up!

However...

richc46 · 27 Aug 2010

Although to me it looks like networking, your driver seems to be up to date.
I checked other drivers in use during the dump, they are fairly up to date. The only real old one that was not a MS driver is this one:

ac97via.sys Mon Nov 22 15:29:55 2004

It is for audio. Although I really feel that the chances of this correcting the problem are nominal; you should always have up to date drivers. Lets give it a try.

Windows says that's up to date too... but I'll try disabling it and living without sound for a while.

richc46 · 27 Aug 2010

Go to the website to update. Do not trust the Windows update. If it is up to date no need to disable. Its not the cause.

higgins · 27 Aug 2010

Since that's integrated audio, I probably need to get drivers for the whole MOBO, but the manufacturer's site doesn't offer any
