Hello, I have an iMac G5 PPC 2.0GHz 2GB RAM. Around two weeks ago I installed Leopard 10.5.6 so I could use the iPhone 4 (which is on it's way). This morning the computer was taking quite a while to start up (2-4 minutes for the grey screen and around 5-7 minutes with just a blue screen). This also happens when restarting. This is a new thing, can't remember it ever happening before (on Tiger and with Leopard since I've installed it). The general use of it on the whole is ok in terms of speed opening and using apps (I only ever usually use Word, Firefox and Mail) but the past day or so it seems to have been lagging a little. I know that the specs are ok for Leopard so I've ruled that out but due to the fact it's now over five years old I'm a little wary that these start up problems may be the start of future further problems. Any suggestions would be helpful. Thanks.
