I have not been able to trace a consistent cause, but a few times a day my laptop will hang for up to about a minute. I can still move the cursor which displays as the wait icon for whatever application I was last in, but cannot carry out any other actions.

Unfortunately I can't Ctrl+Alt+Del to bring up a task manager and I just have to wait.

I can't pin it down to a particular application either, but generally I have either office apps, a browser or other tools open.

I'm tempted to think it may be network timeout on something, as I can't think of anything else which would delay for that long with such a significant impact, but as I'm more a Unix person I thought it would be worth asking here.

You might use Reliability Monitor, see if it shows what is hanging the system.

will try it and pop results back up here as to how well that works. Cheers – Rory Alsop Jan 10 '11 at 19:49
Hmmm - the reliability monitor doesn't show any issues at all on the occasions the machine has hung :-( – Rory Alsop Jan 11 '11 at 8:50
Accepted the answer, as it has finally helped me diagnose the issue by not showing any issues - this helped me narrow it down to network timeouts. – Rory Alsop Apr 19 '11 at 16:46
