I'm sure someone has had this problem before but when running tasks on my G5 tower (namely video rendering in Final Cut Pro) it automatically goes into sleep mode. I'm not even sure where to start. I restarted hoping to clear up things, as my computer stays on most of the time, but that didnt stop it. Normally it runs the task about 1 or 2 mins then just puts itself to sleep. I cant get anything done! any ideas?
