I just checked the perfmon counter and yes indeed they were corrupt, I ran the following commands to fix it
Rebuilding the counters:
cd c:\windows\system32
lodctr /R
cd c:\windows\sysWOW64
lodctr /R
Resyncing the counters with Windows Management Instrumentation (WMI):
WINMGMT.EXE /RESYNCPERF
Stop and restart the Performance Logs and Alerts service.
Stop and restart the Windows Management Instrumentation service.
Thank you very much
