Burn-in or benchmarking software?

[r-sparks]

My new iMac has been crashing a little more than I'd like. iPhoto, iDVD and several dashboard widgets have crashed during general use over the last few days.

Is there any free burn-in software I can use to stress my system, to ensure this isn't a hardware fault? Or is there any trick you can recommend to stress the system? Maybe a terminal script?

You should have gotten Apple Hardware Test with your iMac, but that may or may not detect any problems, even if youhave some dodgy hardware.

Some general maintenance might be more successful... I use MainMenu to repair permissions, clear out cache (including font cache) and logs, validate preference files, etc, every now and then. Crashing apps might just as well be linked to those things as it could be caused by hardware issues...
