Can someone analyze this dmp file?

I have a user with a HP nc8230 laptop. Worked fine until today when he closed Windows Media Player and system rebooted. He had MS Word open and after the reboot he could not maximize the file from the tray. He was also working from an addtional monitor so I got him to change a few settings and then the word file was ok and he was able to view normally.

I checked the event viewer and there was a system error. Ran the debugger tool and got the following. Any idea of what the problem is?

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: 806d0753, The address that the exception occurred at
Arg3: f6bc5c28, Exception Record Address
Arg4: f6bc5924, Context Record Address
