Hi Folks!

Turned on the monitor this morning and - nothing.  Computer was off.  I
leave on partially because of overnight jobs, partially because of turn
-on surges, etc.

Power up; runs a while then shuts down.  No fan revving, no warning, 
just off.  (Great!)

Open the case --  little dusty in there for as new as this machine is.  
Power on; all the fans working.  Good, but odd - figured I'd see a dead 
CPU fan.  Shut down, let come to room temperature, spray with an air 
duster, let come back to room temperature and retest.  Also ran psensor 
to see if anything telling there - guess normal.  Nobody too hot.  Let 
run for a while - no shutdown.

Put the cover back on and back into position (where the computer 
normally is).  Runs a while then shuts down.  Of course!!  Something 
with the cover on? But psensor didn't display any higher temperatures.  
Some utility I wasn't running before?

Unplug and move the computer back to the work bench.  This time happen 
to lay it on its side (it was upright - vertical - before): bleah! Bunch
of dust over the guess intake for the PSU's 120-140 mm fan!  Blow that 
out.  Retest, put back where it belongs.  That seems to have been the
problem!

So a combination troubleshooting tip and question.  If have an otherwise
random/no reason to shutdown issue check the bottom of the computer!
This case has the PSU at the bottom.  Seems to make sense from a
stability issue but mainly got the case because I liked what it looked
like -- quite frankly plain black -- and had the specs I needed,
including sturdiness; plus a low price.

The question portion is anything I can do?  The house has been dustier
the past several years -- others experiencing and have read due to some 
vulcano erupting years ago.  Vent filters on the computer could make air
flow issues worse.  And is there a way to monitor the temperature inside
the PSU?  Is an EVGA or Thermaltake PSU.

TIA!
