Computer goes to sleep during bounce to disk

[Fansplastic]

I just started having this problem two days ago out of nowhere. I will start the bounce and about a minute into the bounce the computer goes to sleep which in turns stops the bounce and i get a 9073 error. I've checked the energy saver preferences and they're all on never and the put the hardisk to sleep is unchecked. Any help on this would be much appreciated

Try zapping your PRAM. To do this, hold down command-option-P-R while the system is booting. Hold the keys down until your hear, at least, 3 CHIMES while the system restarts.

Once you've rebooted, you may need to double-check some of your system prefs.
