Since acbsp.exe is a common target for impersonation, rule out infection first.
Because acbsp.exe is sometimes tied to audio processing:
"The instruction at 0xXXXXXXX referenced memory at 0xXXXXXXX. The memory could not be read." or simply "acbsp.exe - Application Error: The application was unable to start correctly (0xc0000142)."
