-- Thanks everyone for the advice. It was hard to use Activity Monitor because after starting it up, it too would stall. But I've got my iMac running quite well now by restarting, as suggested, from the installation DVD, and doing a Disk Repair (it did need repair). Also I have done the new 10.6.3 update as outlined by Ronni.
-- The problem now is with my 120 Gb Lacie external HD. Until the 10.6.3 update, it did appear on my device list and could be used, though a bit flaky. Now it no longer appears. Is there any way I can force it to appear so that I can use Disk Repair on it? It's got a Firewire connection, if I check Firewire under Hardware in System Profiler, the FireWire Bus shows only 'Unknown Device'. Does this mean the hailstorm might have rendered the HD unusable?
