Windows error messages are better handled in hex.  -1073738810 is
C0000BC6, and a quick Google on that shows it is basically "performance

You can use "perfmon" to explore what counters are really present. 
Perhaps the "privileged time" counter was renamed in 2003.  In your
particular case:

My XPSP2 system does not contain "APC Bypasses/sec" and "DPC Bypasses/sec".
