I have no idea why this has happened, I have googled and found out what the beeps mean but what do I do? Do I have to replace the DIMM? I have opened up the dome and dusted and taken out and put back in the 356 RAM but it still beeps. Can anyone tell me why it has happened - yesterday it was fine.

Did you have any sort of power surge?

If its only 356MB of ram that's gone bad I would buy a 512mb module. they are only $19 or less

Try replacing the PRAM battery too.

Found this very useful info, dated 2003 (some may not apply to MacOS X):
As explained by Sad Macs, Bombs, and Other Disasters (an invaluable resource) the number of beeps indicates a problem encountered by the Mac's Power On Self-Test (POST):
• 1 beeps = No RAM installed/detected
• 2 beeps = Incompatible RAM type installed
• 3 beeps = No RAM banks passed memory testing
• 4 beeps = No good boot images in the boot ROM
• 5 beeps = Bad ROM boot block or processor is not usable.

I take it this is a snow ball mac? by the removed "Dome" There are 2 memory slots and depending on the model there may be a ram size limit on one of the slots.
