Hi again,

  Etc. etc. etc.

At this time ( like in the previous example) I had nothing running.  It 
seems as though when the system starts up, if x gets in first it hogs 
everything, if not everything runs ok, temp of the CPU goes down.  When 
x plays up, it would appear that it carries on "whatever it's doing" 
even while the screen is blanked out cause when I come back the cpu temp 
is up to 59 deg C.

Anything else I can give anyone?

And thanks to those who have already replied!!!!!

Dave
