Ever since my friend's power supply (520ST) blew up when switched on I have
had the feeling that power on/off cycles were more damaging to the power 
supply than the computer or monitor.  At first this may not seem too serious 
but in his case the power supply took the whole computer with it because there
is no overvoltage protection (at least that is the way it appears to me).
Could it be that it is safe to switch the computer and monitor on and off any
way you like but not so safe if the power supplies are switched on/off?
If switching power supplies on/off is less safe does that mean the 1040 is
inherently more at risk of failure in such situtations than the 520 since,
in the case of the latter, the supplies can be left on all the time and power
controlled by the switches on the computer and drives?

BTW I have replaced my computer power supply with a 7A job that has OV
protection (I got it for $25 a few years ago at Canal St. in NYC (it's
surplus)) and feel much safer now.  Next, I am going to replace the mouse
if I can find a nice one that is compatible.  Anyone have any suggestions?
