The fan on my computer is very noisy today. Do you think it is about to give up the ghost, or can they suddenly get noisy. Could it be dirty, or dusty. Any suggestions.

Very likely it is about to die, I always used to replace them at this stage. But last week a m8 of mine discovered that you can often peel the label of the middle and get some light oil in. jema

Can I just replace the fan, or is it joined to a really expensive bit.

Generally there are two fans, north bridge and CPU, with either normally speaking a new fan of the right size can be easily bought and fitted. jema

I've managed to get an old TV working by taking the back off and giving a good vacuum out. If the computer is in a dusty place it might be worth trying to clean it, although if the computer overheats it could cost a bit more than a fan.

Are you saying my office is dusty Proberbly could be because the towere seems to attract the dust like nothing else. Perhaps I'll get the side off and try that first. How long should a fan last, if the computer is used every day.

I have no idea, altough I've never known one go and I've worked with computers for 15 years or so. I've seen screens go, the odd hard disk crash, I've broken a keyboard and when I used to play games I broke several joysticks. As my PC is in the same room as an open fire we get a lot of dust.

I'll try the hoovering trick first then. Hope it will work, it is a dyson after all

I look forward to the 'how to I get a RAM chip out of a Dyson' post tomorrow.

I'm sure you will, but it's always worth backing stuff up (especially anything urgent) and be careful of the chips.

The one thing I often do when adding something to my PC is nudging the Disk cables (the large ribbons) and then the PC doesn't boot and I think B***er, but a quick check of the cables and it all works. Not sure if anyone else has any tips?

Give it a good blast of compressed air to get all the dust out of the case. Careful with oiling the fan as it can leak through and spray across the inside of the case. Take the case of and with a pencil stop each fan in turn for no longer than a few seconds. That will find the noise one

Now I am scared, I didn't even know there was more than one. Do you get compressed air in cans?

One near the power supply. Some have one on or very near the large CPU. I think they can also be near the graphics card in a hi-spec PC and they may also stick one whereever they fancy!

One or Two in the powersupply (one blows out the back and the other may suck air from the inside of the case), one over the processor (blasts hot air up), one over the graphics card (blasts hot air up), maybe one on the front of the case (sucks air in).
