Hi guys,

Most of you who know me round here know that my area of geek-expertise is pretty far removed from anything computer related, particularly when it comes to issues of hardware. So I come to ye almighty wise ones in search of your help [Smile] .

I have an Acer Aspire 5100 laptop - have had it for about 14 months now. In the last couple of days it has started to make a horrible whirring noise each time I turn it on. Like it's trying to clear its throat or something [Razz] It seems to be coming from the fan, judging by feel and sound. The fan still seems to be working, but the noise is irritating and disturbing to say the least. It's pretty much constant and is worrying me more and more. When I blow a little air into the vents, obvious amounts of dust seep out - do I just have a dirty fan that can be cleaned, or do I need to have it replaced?

Furthermore, is there anything I (with my limited, but not entirely non-existent expertise) can do about this at home? Or is it necessary to take it in to be looked at? I'm in the final stages of writing a dissertation at the moment, so I really need it to be running healthily ASAP.

Thanks in advance for all your help [Smile]

UMMM it could be the hard drive failing - make sure that it is the fan making the noise and not somewhere else on the laptop?

Either way you should have everything backed up on something removable if the worst happens.

Sounds like the fan might be going south. If you're lucky, you might be able to find a similar-sized one, though it's highly unlikely - you'll probably need to replace the whole heatsink/fan assembly. The part itself isn't too expensive, around $30 or so, but replacing it would be a royal pain in der arsch. Here's the service manual, in case you decide to give it a shot. At least, I hope it's still there - IT nazis at work have rapidshare blocked off.
