Re: What causes Vista PC to freeze?

First, nobody need be an EE. This is about simple diagnostic
procedures. And anything that might be better solved by an EE - well,
that is what you have in this newsgroup if you provided detailed
information - especially numbers. And for free. Third, that analog
meter belongs in the trash. Even better technology is sold in K-mart
for about the price of a hammer. An analog meter is no longer
sufficient for required numbers. Even auto mechanics now routinely
use 3.5 digit multimeter - they are that ubiquitous.

To reply means making assumptions. For example, does not matter
whether you brought an ethernet cable. To provide useful information,
defined is what happens when NIC is connected to router or modem. And
then what happens when only cable is removed. And again, but without
the NIC card. An existing cable in their house means your missing
cable is irrelevant. And then repeate same tests when in your home.
Also confusing - is the Wifi and NIC the same PCI card? Not stated
when it must be. Vague posting force too many assumptions.

For example, one type failure means the first computer connects to
the router without failure. That same defective modem connected to
the second computer - with same defect in its NIC - means second
computer fails. Then both computers work just fine at your place. To
have one computer fail means both defective must exist in the
configuration. This posted previously. And with what was posted,
nothing useful disputes whether this failure example exists.

Also confusing - the second computer fails when only connected via
Wifi? That also is not specifically states leaving me to assume both
a yes and no answer.

Why do I need answers that detailed and specific? Information this
vague routinely leads to too many assumptions and completely
irrelevant conclusions. You must literal state what connects to what
and then what happens - good or failed - to obtain a useful reply.
And nobody needs even technician training to obtain a solution here.

Currently there is no information sufficient to replace anything.
And not because that information requires technical abilities. What
you did and did not do is too vague. And don't replace anything until
we have a suspect.

Using that third paragraph as an example, replacing the router would
make it work even though the computer is still defective. Or maybe
not because, well many posts do not differentiate between test using
Wifi, or test using an ethernet cable, or a test with NIC removed.

Now assuming a completely different interpretation from your post -
well what is not booting? Does the computer actually boot but lock up
long after booting - and you called that no boot? IOW once you see
the Windows logo, then the computer has booted just fine - even if the
computer fails later. IOW exactly where does the computer stop?
Another example of why a useful reply is subverted by too little
information. Do not assume you know when booting ends and when
Windows configures itself. Currently, you have repeatedly posted that
the Windows logo never appears when the NIC is installed - which makes
no sense considering other observations. So maybe the meter was never
needed because the computer was booting every time? Again,
information posted is woefully too vague to obtain useful replies.

Even that 'analog meter' makes no sense because such meters were
obsoleted so many times as to be almost useless for most technologies
- even beyond computers. But then, the request for voltage numbers
may be completely unnecessary. You posted 'no booting' when it booted
every time? Just another still unanswered question because posts have
been too vague; contained too many contradictions.

Every test must be detailed as to even what was enabled and what was
connected to what. Nothing posted required even electrical technician
knowledge. Anything you feel is unimportant is usually the most
important request. IOW every question requires an answer – especially
those that make no sense to you. Your posts contain too many
contradictions and include too many useless observations (as
deomonstrated by the above third paragraph example).

I really appreciate your persistance in trying to help with this problem,

The person I am using has a degree in Avionics so I have to asssume he knows
what he is talking about, and I don't have the qualifications to question
his judgement. His multimeter was analog so it would be difficult to get a
2 decimal place accurate reading anyway.
There are two computers at their house. One is connected directly to the
modem. Everything works.
The other boots properly if there is no wireless NIC or modem in the PCI
slots on the motherboard. It does not boot if they are installed. I did not
bring a network cable to test if the onboard NIC worked. However, this
computer works properly at my house with the PCI cards installed, using
wireless or the LAN cable.
The only thing that seems different is their vs our router. Theirs was on,
ie powered up therefore broadcasting, but not connected to their modem. I
did not turn it off because I didn't think about it while I was there. I am
waiting on their decision as to what they want me to try next. My thinking
is to replace the router.
