I've done all the searches on the subject but can't find a solution. I'm getting the two tone alarm sound from my PC whenever i'm downloading to I-tunes/virus scanning etc. This seems to have got worse over the last few months with the alarm kicking sooner all the time. The fans are all working ok so i get the impresion nothing's over heating. Could it be a fault with the temp sensors and/or can they be adjusted?
I'm open to any suggestions as to what the problem is.
