Vista - Computer dies

I have a Vista Business 32-bit computer which shuts down after about 20
minutes with no warning of any kind, as if the power has suddenly been shut
off. Are there any log files I can look at to see if there is any indication
what the problem is?

My guess is that it is the power supply, but I am reluctant to buy a new
supply in case it is something else.

The computer is permanently on, (apart from a couple of hours every week),
and has been working correctly for nearly a year, so has probably been
switched on for over 7,000 hours. Is that the life expectancy of a power
supply?

As well as checking the internal fans for cleanliness, make certain that the
heat sink on the CPU is not impacted with dust/crud. This will prevent
proper cooling even if the fan is doing as it should.

Click on Start Icon
Type Eventvwr on the start search box and enter (or Windows button + R) and type eventvwr
Check the windows logs ( Security - System & Application ) if there are any error logs post them here.
Then scroll down to application and service logs.. check for any errors there?
post them here too.
if you have checked for any errors that belongs to hardware you might also download Hiren CD as bootable CD when you boot up using this CD you will have great number of tools to test all of your hardware components...
You can use Memtest program to do so, as it is one of Hiren CD tools included there.

Please Post your feed back

I agree with the other posters: this is almost certainly an overheating
problem. I bet your processor fan is broken, or covered in dust, or the
processor heatsink is dusty.

You can do a reasonably good job with one of those compressed air cans,
although removing the fan and heatsink altogether for a proper clean is the
best approach. It also lets you renew the thermal paste between the
processor and heatsink, which can degrade over time.

Thanks to the four people who have posted suggestions. As we are having
much hotter weather than usual overheating may well be the problem, although
the CPU and PSU fans seem to be working correctly, I will have a go at
running the computer with covers remved to get more air to it to see if that
makes any difference.

The errors noted in the log file are as follows :-

I think the first one has appeared just before shutting down the last couple
of times but I only seem to have about half an hour in which to work with the
computer before it shuts down.

The fans may well be turning, but if the CPU heatsink and power supply are
full of dust, they will have little or no effect.

Removing the side of the case will make a small difference maybe, but it
also changes the flow pattern inside of the case which can make hard drives
run hotter than they should..
