Watching a live video it suddenly lost the picture and displayed a dark-grey screen saying “Aïe! Aïe!”.  Trying to restart it from Apple menu, empty grey screen and triple sound of alarm repeated every 5 seconds. Meaning? 

Am I right in fearing the worst and thinking I need the help of a specialist?  Many thanks for any reply.

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

You're welcome!
