Re: Please diagnose my problem!

Many people will say it is this or that. IOW they are
guessing. They are also expert automobile mechanics. Worse
still, they will not even say WHY it is this or that which
means wild speculation.

If somehow the BIOS got changed, then reset the BIOS to
defaults ... AFTER recording what was originally in that
BIOS. Some BIOS defaults are intentionally different to
correct hardware incompatibility problems. Always record all
previously information before changing anything.

Try swapping memory SIMMs to get the machine to boot. If
swapping solves a booting problem, then one of those SIMMs is
probably defective.

A long list of reasons that could create the failure. So we
don't yet even worry about fixing the problem. First we must
understand it. For starters, what does the error message
say. Many will just say to do this when you get that
message. IOW they speculate. But the message suggests a
computer program tried to access memory that was illegal to
access. So why did program do that? Memory error? Defective
software? We don't know from what you have reported. So we
move on to collecting relevant facts - and don't yet try to
fix anything.

What does the Event (system) log report? Was this due to a
problem that your system had seen previously and had
previously worked around? Information from Event log is
necessary to diagnose the problem. See help (if necessary) to
find event log.

Also perform a quick check of the Device Manager just to
verify no defects were detected by the system.

A responsible computer manufacturer provides a comprehensive
set of diagnostics for the machine. If not provided, then you
must download and execute those diagnostics from each
component manufacturer. Especially important is the memory
diagnostic such as by Docmem or Memtst86. Run a memory
diagnostic first at normal cooler temperatures. Then repeat
the same diagnostics with memory chips heated by hairdryer on
high. That heated memory is quite normal temperature to
semiconductors (see data sheets if you doubt it). But
defective memory becomes more obviously defective when hot.
So heat it to temperatures that to you is uncomfortable to
touch. Good memory works just fine at those temperatures.
Intermittent memory becomes more failure prone and is easier
to detect with a memory diagnostic.

Why do you think others hype fans. They had problems.
Instead of fixing the problems, they cured the symptoms - more
fans. One chassis fan is more than sufficient cooling for
most computers. Two fans is only redundancy. Heat is also a
tool to assist diagnostics in finding intermittent defects.

Get diagnostics for those other system components. Notice
we first verify hardware integrity before even looking at or
suspecting Windows or software.

Meanwhile, buying a second power supply is usually wasted
money advocated by those who don't first collect facts. The
integrity of the power supply and other components of a power
supply 'system' are better checked in two minutes using a 3.5
digit multimeter. Yes, you replaced a power supply but other
components of the original power supply system remain. Not
that this would be a reasons for your problem. Some
procedures to see if both supplies are (were) good
accomplished in but 2 minutes:
"Computer doesnt start at all" in alt.comp.hardware on 10

"I think my power supply is dead" in alt.comp.hardware on 5

However in two minutes by only recording voltages (on red,
orange and yellow wires), you will probably discover power
supply system is and always was OK.

One last thing. Write down what you see. Numbers in that
original message that may have better identified what to look
for. But you did not record those numbers. Numbers that mean
nothing to you might have accurately answered your question in
a first shot. Collect facts. Fixing the problem comes later
once we have identified a real suspect - and not wildly start
replacing power supplies only because some Uncle Ned did that
previously.

Even if the collected data means nothing to you, that data
does provide those who 'answer without speculation' the
necessary tools to therefore bother to reply. Currently the
information as provided got previous responses of same
integrity.
