For the past 3 nights, at exactly midnight, my iBook G4 running OS10.5.6 has crashed (screen goes grey, tells me to restart).

I'm thinking I'm probably going to have to reinstall the OS, unless anyone has any brilliant and wonderful ideas that I could try before going to all this effort?
 
I haven't the faintest idea why in reality, but off the top of my head it may be something to do with the internal clock not functioning properly, doing something weird when it resets for the next day thus causing the crash.

My first thought would be that the cron scripts. There are maintenance scripts which run automatically - daily, weekly, monthly. Each cycle performs different types of actions, with weekly being the most intense.

However in my case the daily script usually runs at about 3am, so I'm guessing everyone's daily runs at the same time. Not sure what could be triggering at midnight in your case. Maybe a virus scanner trying to update virus definitions?

Think about what could be self-updating and try to look into that.

Also I would suggest that you boot from the DVD and run Disk Utility > Boot Drive > Repair to make sure you don't have some kind of disk problem as the cause.

I don't have any virus scanners, so it can't be that. The drive seems also to be fine according to Disk Utility.

Adding to the above, check your console logs, see if there is a recurring thread when your comp crashes.

How would I go about this? I open Console and it just showed me what software updates I've done since installing the OS

Your comp is Cinderella, gotta be off by midnight! :p
 
Well I spent my evening reinstalling the OS and reapplying my settings again.

Thanks for all your help anyway!

I can't believe you have 10.5.6 running well in an ibook G4...thought
it would be too much.

Runs just as fast as Tiger did, maybe faster!
