Well, you're right about not considering all the possibilities and
people only posting what they understand. To allow for this
eventuality, I have cross-posted this on <sci.geo.meteorology> to see
if current weather conditions (I live in South Fla) might contribute
to the problem, <sci.astro> and <sci.physics> to rule out any astral
or interstellar factors, <alt.sci.physics.acoustics> in case its a
localized problem with ambient noise, and other usenet groups too
numerous to include, lest the ones I inadvertently leave out become
offended by my ommission :-)


  First collect facts.  For example, what do system (event) logs
report? Does Device Manager report any hardware failures or
conflicts?  It is an HP.  Therefore a responsible computer
manufacturer provided comprehensive hardware diagnostics - for free.
Diagnostics execute without Windows that complicates testing.  What do
those hardware diagnostics report?

No system event logs, error messages, or other reports have ever been
generated, especially when the PC reboots fromthe bios setup menu.
None. Zilch. Nada.

  Power supply may have been defective for months.  Defective power
supplies can still boot a computer.  But voltage numbers using a 3.5
digit multimeter could have discovered a problem then, AND determined
if the power supply 'system' is defective now.  System?  Yes, power
system is more than just a power supply which others often do not
know.  Which system component is defective OR can you say without
doubt that all system components are good?  Needed are definitive
answers such as numbers provided by "When your computer dies without
warning....."  starting 6 Feb 2007 in the newsgroup  alt.windows-xp

I'll get back to you when I follow up and accomplish this suggestion.


  Paul has also noted another reason for system instability.  Any
bulging on capacitors (especially near the CPU) is an indication of a
pending hardware failure.

 If dust was a problem with a computer in a 70 degree room, then the
computer has been defective for a long time.  Computers must work just
fine even in a 100 degree room.  Executing comprehensive hardware
diagnostics while computer is in a 100 degree room is another way to
find the current failure OR locate impending failures.


As I stated earlier, I just about emptied an entire can of compressed
air on all moving blades, fins, grills, filters, and any other part I
found inside the PC case. No effect. BTW, my PC is located in a room
that manages to stay at 73 degrees.

  Even a defect in the video processing system could cause your
failure.  Those who wildly speculate did not even know that?  Well,
many will reply.  But only a few really demand facts to provide
definitive answers.  Posted are how to post useful facts (especially
numbers) so that following replies are useful.

I check this nsg daily to see when others reply and what they suggest.


  Once hardware is exonerated, then move on to other software
suspects.  Provides is how to get definitive answers - not
speculation.

I agree, except I worked it backward, by first considering software
then hardware.
