my next move is to checkout ,or replace the power supply?
if thats ok then the only thing left that i can think of is a fault in the mb?
Again, you are speculating. Some of the things declared OK are
(from what I read) are still unknown. Don't replace anything.
Shotgunning a power supply may only complicate your problem and will
not provide a useful answer.
In that last post, I asked some questions. Those questions were not
rhetorical. Questions you should have had answers for long ago - in
order to "follow the evidence". For example, the computer was beeping
repeatedly. Now learn beep language. But which dialect? Well, what
is the BIOS manufacturer? Notice the difference between your
procedure of only speculating (sometimes in direct contradiction to
the facts) and then testing; verses the method recommend - "follow the
evidence".
Again, much of those facts - especially numbers - are how you get
replies from the better informed.
Asked was about reports from comprehensive hardware diagnostics.
That also was not a rhetorical question. You cannot selectively
answer questions and expect useful replies. Every question asked was
laser burning into your problem. And it it sounded hard, then it was
the better answer and, BTW, was not hard.
Again, your list of 'accomplishments' is near zero. HD was
completely irrelevant - should not have been tested.
Memory (ram) remains "unknown". Your testing procedure does not say
memory is good. I don't remember if I posted a 'definitive'
solution. But swapping parts did not prove anything 'definitive'.
Your later posts suggest memory was not even involved. Again, nothing
accomplished.
How did you check cables? Not that cable have anything to do with
BIOS crashing.
DVD and CD Rom completely irrelevant, not even on the longer list of
potential subjects, and again nothing accomplished.
Changing what BIOS boots from - irrelevant since you have a beep
code. Long before anything was booting, a complete failure was
detected and reported. Nothing accomplished since you still don't
speak beep.
Drivers checked? Checked for what? Drivers are relevant only
after booting. Your failure occurs before booting. Again, nothing
accomplished.
PC health OK? What says that? Did you run the manufacturer's
comprehensive hardware diagnostics? I don't see anything that says PC
health is OK - especially since he machine intermittently does not
boot.
No events in system (event) log and no problems in Device Manager.
Right idea. Then later, the problem was occurring before booting
meaning that Operating System information is irrelevant. You have a
hardware problem before any software loads (according to how I read
your posts). Therefore why are you looking at Windows? Again,
nothing accomplished.
Swapping a power supply does nothing. The original post says
exactly what is necessary to make 'definitively good' the one system
(more than a power supply) that can make all others defective. "When
your computer dies without warning....." starting 6 Feb 2007 in the

Disconnect nothing. Get numbers. Get conclusions from those
numbers AND get useful other information by posting those numbers
here. Again, did you read the short list of potential suspects in
that original post? All that labor ignores facts on the table (in
that original post) and therefore accomplished nothing useful.
You are randomly 'checking' things. Stop analysis by wild
speculation. Get facts (ie beep code). Follow the evidence as is
even taught in a TV show called CSI. Provided was the short list of
potential suspects. That is where you should have been looking. Of
course, that two minute procedure should have been done long ago.
