It looks like you've already made up your mind, but if you want to verify something it might be worth checking the system by booting it off the MorphOS CD. If that works then it's likely just some 3rd party component or installed software that's messing things up and it should be possible to either reinstall or figure out which 3rd party component is causing the trouble.
If the CD booted system crashes a lot as well then it is likely that the HW is having issues. Finally, MorphOS does have bugs and you might have run into some. If it is reproducable issue (with a CD boot or fresh install, and doesn't appear to be a HW issue) we'd be very interested to get a bug report about it.
Support is available via a mailing list and some other channels. In most cases visiting freenode #morphos IRC channel (european evening hours) will get your help the fastest.
