>> How many beeps? The beeps should match the number of flashes plus one longer flash; there will be one long flash, then a number of shorter flashes; the shorter flashes are what should match the beeps. If there are 1 to 3 beeps, it's probably a problem with your RAM... <<---------------- Kynan, That's fascinating. I had never come across anything suggesting that there might be troubleshooting data within the flashing-light sequence. Is this posted somewhere on the Apple KnowledgeBase? I am not finding it in searches, if it is there. Can you send a pointer to the relevant document? Thanks, Jerry
