<br>You must understand that I am quite ancient and my memory goes back to<br>the days before transistors were invented. We used 'valves' or 'tubes'

personally leave my machine on 24/7 and have done for the last 6 years
or thereabouts. I've only had 2 pieces of hardware fail on me, and both
of them have been sticks of RAM. Maybe I'd have had more failures if
the machines had been powered down repeatedly, and maybe not.<br>

Slightly related is the policy at work for the desktops - they are
turned off each night. The mainframes however, are never powered down -
we can't afford for them to not come back up when they switched on, and
the cost of that potentially happening far outweighs the added expense
of the air-con, machine-room staff, electricity, stand-by generators and so forth.<br clear="all"><br>-- <br>Steve<br>Despair - It's always darkest just before it goes pitch black...
