thank for your help

The Answer is :

 
  Please contact your hardware support organization for assistance with
  this and with any other apparently-hardware-related errors -- this
  message is usually associated with DECevent or Compaq Analyze output
  for a machine check, with the usual supporting text for the machine
  check -- as displayed by the bit-to-text error log translation -- being
  "IOD-Detected Hard Error -OR- DTag Parity Error (If Cached CPU)" or
  similar.  Machine checks are -- as previously discussed here in the
  Ask The Wizard area -- usually either hardware errors or (potentially)
  very low-level software errors.
