iMac sleeps at random

[AppleMan101]

iMac G5 2GHz 20" ALS

My iMac has started to go to sleep at random and then refuses to stop trying to go to sleep unless it is restarted. It will wake for 30 seconds or so then go back to sleep with no prior warning.

any ideas?

Take it in to an Apple Store. You may get a free repair:

Don't forget to make an appointment, or you may have to wait in line for a while.

It isn't shutting down, merely sleeping...repeatedly. so the above action does not apply to me even though my computer is eligable for the power supply replacement.
