Thanks!

The attached DMP file is of the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e) bugcheck.

This indicates that a system thread generated an exception which the error handler did not catch.

BugCheck 1000007E, {c0000005, 82e24734, 8ab1f648, 8ab1f220}

^^ The 1st parameter of the bugcheck is c0000005 which indicates an access violation occurred, let's see what caused it:

:kd> .exr 0xffffffff8ab1f648
ExceptionAddress: 82e24734 (nt!RtlEqualUnicodeString+0x0000002f)
   ExceptionCode: c0000005 (Access violation)


It was caused by RtlEqualUnicodeString which is the routine compares two Unicode strings to determine whether they are equal. Most likely a device driver related issue.

Remove and replace avast! with Microsoft Security Essentials for temporary troubleshooting purposes:

In your loaded drivers list, dtsoftbus01.sys is listed which is the Daemon Tools driver. Daemon Tools is a very popular cause of BSOD's in 7/8 based systems. Please uninstall Daemon Tools. Alternative imaging programs are: MagicISO, Power ISO, etc.
