Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
Did you get any of the Install Discs with the Macs?
On the one with no Utilities, might try reapplying the big combo update...

on the one computer with the beeps the LED also flashes 3 times my son says it's 4 but i think that it the stop that he is counting cause it starts over and flashes. can you tell me what that is, and how can i fix it. my son was right about the flashes and i see you told us about it. 3 beeps = no good banks. what is that? how can i fix it, and about the DVD is stuck open it try's to close but it looks like the drive stop's it. is their a way too stop it or fix it and i just use a outside DVD drive or player. you were so helpful they ( apple ) should put you on the clock.

Well, it sounds like bad RAM/Memory, (banks is refering to the RAM or the slots), tough to tell what it is.
Also, those beeps are for really old Macs, it would help if we new the exact model...
If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...
