<p class="MsoNormal">ok Thanks Martin it is resolved. initially IOdelay shoots to 60 precent but gradually it decreases and in a mint or two it reaches 20% and things got fine. Thank anyways. can you please tell me one more thing what is this IO delay . it
is a IO of HD ,Processor or LAN card or mixture of all together ?</p>
