Sorry for shouting but I'm desperate... Macbook repeatedly plays startup sound, sometimes cutting the sounds short and playing again and again. I have tried EVERY possible action... I am nowhere near a mac dealer or tech as I live in the woods. Hitting apple key+start does nothing...I did a bettery check, a power check (removing batt and holding power button 5 secs) I held down the power button for 5 seconds, got the loud beep.. then it restarted over and over until finally showing the apple Logo on a grey screen, then in 5 different languages a text telling me I need to restart my computer... Apple key+s or any other key along with the apple key yeilds nothing... This system is 6 months old and used mainly for photos and browsing the web......Absolutely no downloads, or upgrade stuff other than the obvious recommended ... ANYONE?
