Computer dies

V

Viv

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?

Sounds like an overheating problem.

Have you opened the computer up to check for dust accumulation?

Check all the fans for sure, especially the CPU fan. It might be
clogged with dust, or might just have died or is running very slowly.

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.

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.

I think the first one has appeared just before shutting down the last couple

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..
