Twice in the last few months, after a blue screen and a re-start, the tower started to make a fairly loud buzzing/whinning noise. Upon another re-start this stopped. Do I need to worry?

the noise is almost certainly fan-related, and you should open the case to have a look.

Turn the computer on so the fans run, and check that one of them isn't being obstructed by a wire or cable, or even contacting the plastic casing over the rotor. Modern computers have more than one fan (mine has five) and it's common for one to play up.

The fact that you had a BSOD might indicate that the processor fan is in difficulties, and you would do well to replace it as soon as possible - just as a safeguard. They aren't expensive.
