Strange Sound Issues with FS415B - Please help before guarantee expires!!!

[Boris71]

Hi, hoping someone can help, please?
Had an FS415B since February of last year and everything's been fine, but over the last week or so a strange problem has begun occurring with the sound - it's similar to the sound you get when a vinyl record is sticking, but at a very high speed - something not unlike the effect they used in Max Headroom (for those that can remember).
I noticed it on some MP3's I'd downloaded, then on some live streamed music and now it's even occurring on the start up chimes - a kind of sticking distortion.

Can anyone help, the guarantee runs out very soon and I need to get it looked at if it's not something I can sort myself?

Thanks in advance.

Sorted!!!!
Cheers guys, much appreciated - the defragmenting didn't cure it (although it was definitely worth doing as it turned out), but deinstalling the drivers of the Primary IDE and rebooting seems to have done the trick.

It was really beginning to annoy and I thought it'd have to go back for some hardware repair, so thanks for everyone's assistance.
