pc shuts down on its own

[Phil]

Can anyone help me please
Does anybody have any ideas as to why my pc shuts down
all on its own?
It is just as though you have switched it off at the
mains, it does this randomly without any warning, it
doesn't go through the usuall shut down procedure, and
will only restart if you first remove the power lead from
the wall socket and leave it removed for a few seconds,
and then it sometimes doesn't restart first time it just
runs one of the fans for about 3 seconds then nothing, I
then have to remove the power lead and try again.

Thanks Phil

Phil;
Heating issues can do that.
Is the computer in a cabinet?
If in a cabinet, the back should be open with at least a few inches to
the wall so air can circulate freely.
The front needs to be open as well.

Check all vents and make sure all are clear and free of dust etc.

Open the case and verify the fans are working.
All power supplies and many video cards and processors also have fans.

Thanks for the advice

All of the fans are running fine

The problem even occurs with side panel of the case
removed and the machine sat on the table in plenty of
free space

I had the same problem with an Event ID 1003 and (102),
there are to many hardware issues to be sure which could
be yours with certainty but...the basic suggestions i've
heard sound legit. My problem was diagnosed throught the
Microsoft help engine as an iomega active disk problem, I
was directed to iomega's site for an "appservices" file
which I ran but still was having unexpected shutdown
problems. Then I installed XP service pack 2194, still had
the same problems. Then I swithched my new Nvidia 5600
Extreme 256mg card for my other computers ATI Radeon 9200
128 mg card, STILL HAD SHUTDOWNS. To make a long story
short, I did everything but buy a new motherboard. I
finally downloaded a driver for my VeiwSonic A90f Monitor
and haven't had problems...as of yet. I am keeping my
fingers crossed. I can't say which solution solved my
problem but mentioned the last fix for you. Hope you don't
give up.

try another power supply

Still seems like a hardware problem.
But if you have access to another hard drive, you can temporarily
install Windows and see if it still happens.

Power off, disconnect power.
Open case and reseat all cards and cables.
If you have multiple memory sticks, remove them one at a time making
sure to stay at least Windows XP minimum of 64mb.
If not memory, my guess is power supply.

See if anything here can help:

I was wrong about the problem with my machine shutting
down on it's own. I was also getting BSOD with different
errors each time, additionally upon restart I would get
a "Window just recovered from a serious error" message. I
thought I had the answer with a monitor driver download
but shortly after had the same problem. Well I have now
been running fine for hours and have had no symptoms of
the previous problem, but... I had to take the
motherboard out of the offending computer, put it in
another computer case. I suspect that the problem was
with the power supply. I used to buy the power supply and
case seperately and whenever I upgraded the case I would
sometimes just take the power supply from the old case
and use it. The power supply was good for a year or more
but I imagine something inside burned up or something.
Very confusing since it would partially work which is the
BIGGEST HEADACHE trying to figure out.
