Is your PC taking it upon itself to soothe you with the lilting strains of Beethoven? Do not be lulled into a false sense of security. Your PC is about to die horribly.

Check out this FAQ posted on the Microsoft support site. If your PC suddenly bursts into song it's for the following reason:

"During normal operation or in Safe mode, your computer may play 'Fur Elise' or 'It's a Small, Small World' seemingly at random. This is an indication sent to the PC speaker from the computer's BIOS that the CPU fan is failing or has failed, or that the power supply voltages have drifted out of tolerance. This is a design feature of a detection circuit and system BIOSes developed by Award/Unicore from 1997 on."

Of course it is. Or is it? ®
