After checking my computer using Vista checking tools I founds that I was getting errors with “Avg Disk Queue Lengh”,

after spending quite a lot of time using google and checking the HD , defragging etc etc I found or suspected that it was due to the raid 5 setup,

As raid 5 is rather complicated for a MB set-up and it was having a  hard time running it, so I switched back to a raid 0 setup This i was able to do using the software included by Nvidia except that it is now a 3 HD raid 0 as it’s unable to otherwise

The problem has not only gone away but I can even see a speed difference in the normal computer running, things are far faster

Next step is to install a raid card rahter than the MB doing the job, next post ……
