That means it's time for a really basic bit of computer maintenance.
Clean it.
Yip, get out a bucket of water and a sponge and get cleaning.
Not really, but it is time to get some canned air, take the covers off the side and clean out the dust filters and fans.
If you computer doesn't have dust filters, then now would be a good time to find some and fit them.
This is a very easy job to do, and if your not confident about removing the covers then any half decent computer store will be able to do it for a very small cost.
The benifits can be huge.
My system just started badly mis-behaving, it actually locked up a couple of programs and then refused to restart.
A quick check of the temps using speedfan showed CPU temps were idling around 60deg C. This is way to high!
So I removed the side cover and used canned air cleaned on all the intakes and fans, dislodging a lot of dust in the process that was blocking everything up, preventing in air flow through the case.
Idle is now around 38 deg C, much more acceptable, and the computers performance has returned to its normally speed.
If your on the wrong side of the world, and descending into winter, there is no reason you can't to this as well.
And don't think you have a perfectly clean house and there won't be any dust.
If your system is more than 12 months old, it will be dusty. Even if like mine, it sits on a clean desk.
