First check your panic.log in /Library/logs



A similar thing happened with my brother's iMac and he found the Ram wasn't seated correctly. Try unscrewing the cover below the display and take out and reinsert the Ram. You should put the machine face down on a cloth to do this and unplug it.

Yup, this is a kernel panic. It's often an issue of RAM, like Marvin said. It may be how it's seated, but it could also just be bad RAM. If it's not seated properly, it should work fine once you fix it. Otherwise, take one stick out at a time, test start-up, etc. Switch the sticks around-- it's either the RAM, or the connector they attach to. Hope for bad RAM.

I seemed to get lots of kernel panics after installing konfabulator, after I deleted that I was ok, my old USB alcatel modem software did the same
