THanks for such a detailed response that was great. I know the PC is not
overheating, I have a thermometor on it, I know sounds funny, but I bought
one of those indoor outdoor types and put the probe as close to the processor
as possible, ran it out the back adn the thing sits on my desk and usually
about 80-85F.
I took the PC apart adn cleaned out all dust adn fans, I have a multitude of
fans on it, as the particular PC (I built it) tends to run hot, so I am
usually quite in tune to it.
Last I had it appart I did not notice any bad cap issues, but - I think I
need to take a better look.
I was thinking of bad POwerSupply, it owuld not be the first time I have had
to replace the PS on this thing, I think I replaced one about a year or year
and a half ago.
The funny thing about this shut off is the same error every time, and it
always does it when I am on IE.....IE stops responding, then it shuts off.
I am very very cautious of backing up data, I have several viable backups to
choose from in the event it goes bad or I get a wild haior and rebuild it!
(been known to spend a Sat or 2 redoing that!) the problem with rebuilding
is the 4 monitor setup and getting the drivers just right and installed int
eh correct order!
Thanks so much again, I think the bad cap or PS might be my issue.

Over the last month or so my computer has started unexplainably just shutting

test and it was ok.
I defragged and all is ok, event log shows and error event ID 7026 with the
following message:
The following boot-start driver(s) failed to load. PCLEPI
I can not find anything concrete on how to repair this issue. My computer
will become unresponsive (usually in IE) and then shut off as described
above.
Thanks,
The two tone ("European police car") sound, comes from the BIOS
and hardware monitoring. It can occur if the processor Vcore
voltage is an abnormal value. Sometimes that is caused by
bad capacitors next to the CPU socket. (The Vcore regulator can
no longer maintain a stable voltage to run the CPU, and when the
voltage is far enough out of spec, the BIOS raises the alarm.)
Some computer models are notorious for the "bad cap problem", and
Googling the computer make/model number and "bad caps" may tell you
whether that is a possibility.

A second reason for the police siren, is overheat. Since your computer
is shutting off, that might be the overtemperature protection taking
effect. So the siren sound is warning that it is getting pretty
hot, and when it gets real hot, it shuts off. Reasons for this,
could be the CPU fan has stopped turning, or the clip that
holds the CPU heatsink in place, has broken.
In this example, the clip is metal. It mates with anywhere from
one to three plastic tabs. If the plastic tab snaps, the clip comes
loose, and there is no downward force, to keep the heatsink in
contact with the CPU. Then you hear sirens and the thing shuts
down, when it gets hot enough. In extreme cases, the heatsink
can fall off entirely, and as it falls, break other components
inside the computer.

There are many different styles of heatsinks and attachment
mechanisms. If you'd mentioned the make and model of computer,
it might have been possible to provide more relevant pictures.
Not all computers have overheat protection. Probably anything
in the last five years is a good candidate for being protected.
But some older computers can fry the CPU, if the heatsink
falls off. The fact your computer has shut off, means it
is probably protected and has demonstrated that the
protection works.
For either of the above possibilities, you need to take
the side off the computer, and have a look for signs of
damage. That will help confirm either an overheating
problem, or a leaking capacitor problem. If your visual
inspection doesn't show anything, at least you have a
good set of symptoms to describe to the service shop.
Shutting off abruptly, is not good for the file system on
your boot disk. Enough of those events, could corrupt the
disk, such that it won't boot any more. Make sure you
have a backup copy of your important files, since your
computer is not healthy right now. If you need to take the
computer in for servicing, it also helps to have a backup
copy of your files, since some computer stores have
been known to reformat the hard drive, as a "service"
to their customers. To prevent loss of important files,
you should have an external USB interface hard drive,
with a copy of your email database, and documents stored
on it. Make a backup copy, before taking the computer for
service.
