If you just want a quick list of shutdown events try uptime.exe with the /S switch.-Stoic Joker
DOH! Forgot about that but I'm not sure that it's going to be 100% accurate, eg.

The above Critical event is due to a power outage, when I ran
uptime /s it crashed and terminated when it got that event:

And the time was way off, (~9 hours).
Of course, it could have crashed due to something it didn't like on my system but then again ...
Look at the Event Logs

Thanks for that. I found two unusual events (see screenshots below).-dr_andus
SJ suggested the Event logs originally
Firstly, in the ECEEventLog (whatever that is), for the last 5 days I have 743 events, and they all seem to relate to ATI.ACE.CLI.Aspect.DeviceDFP.Graphics.Runtime.RT_DeviceDFP, which seems to point to my ATI Radeon graphics card. Is that bad?
The ATI graphics driver restarts itself whenever it suffers a critical problem, IIRC.
More interesting:
Secondly, under Administrative Events, I have 2374 errors (out of 2,445 errors in total) for the last 7 days, produced by Apple's Bonjour Service. I imagine this is for syncing with iCloud (which I don't really use), and checking whether I have the latest iTunes (which I don't really use). Is this something bad enough that it would be better for me to block this somehow?
These events are happening one minute before the ATI driver has a hernia. Can you check to see if that trend is followed with prior events, (the sample on the captures is rather small) ?
The Bonjour service is used to discover any other Apple devices on the local network and setup communication with them, (IIRIR). If you don't use iTunes I'd be sorely tempted to remove it and every trace of it, including Bonjour.
