Post by Robert in CAHello Paul,,
Thankfully, you responded!
I thought I would never hear from you again.
I did try Mixmin as you suggested awhile back
but couldn't get it to work but as you say it's
gone also. What about blocknews as suggested?
I don't have problems with the computers and I continue
to runs scans daily and do the mrimgs. (attached log) but
as I said I was afraid to open up the computers and vacuum
them with the mini-vacuum for fear something might happen
and I couldn't reach you for help.

So should I go ahead and do it?
Thanks,
Robert
Here's a page to read first.

You can of course open the PSU, but you must observe some precautions.
First (obviously), unplug the unit. Leave it unplugged for 15 minutes
or so. In most PSUs there are bleeder resistors that will bleed down
the stored voltages inside over time BUT THERE ARE NO GUARANTEES!!
When you open the unit, understand that there are two hazards:
Stored high voltage (200V or so) on the "input" side of the unit.
Stored high currents (tens of amps) on the "output" side of the unit.
The high voltage represents an electrocution hazard. The high current
represents a burn hazard should something metal (such as your ring or
watchband) touch the wrong terminals.
If you just need to move/secure a loose wire, you should be able to do
that without touching any bare wires or terminals inside the box. If
necessary use an insulating stick (eg, a tongue depressor or
chopstick) to probe and move things around. Be wary of using something
like a pencil (the lead is conductive) or a ball-point pen (which has
a metal tip and often other metal parts). And, of course, screwdrivers
are almost always metal and a hazard inside.
Be sure to close the unit back up before you apply power again. It's
too easy to "jump ahead" and apply power with the unit open, then
"remember something" and reach inside the live unit without thinking.
