My Macbook is not booting up. It shows a folder icon with a question mark in it and makes a clicking sound, but that all.

I’ve already mailed it to Apple to fix a similar problem before (logic board), but my warranty ran out in June of 2007.

I’m not sure what to do now.

Thanks

Boot from the OSX DVD and go to Utilities > Disk Utility.
Repair permissiions and repair Disk.
See if it works.

Fixed title...

And once you run Disk Utility as Dr. suggests, you'll have a definitive go/no go indication. It's probably just a glitch that DU can fix. Good luck!

Try reseting PRAM. Restart computer with the Apple-Option-P-R keys held down.

Then try resetting NVRAM. Restart computer with the Apple-Option-O-F keys held down. If you have an Open Firmware password enter it. At the command prompt type "reset-nvram" and then "reset-all" to reset it.

This solved it once for me.

Intel macs don't have Open Firmware

It's clicking is it? Sounds like the hard drive may have failed. Do you have backups?

No, but that's the wording to search for in Apple's knowledge base. Too many people think of it in those terms to change it overnight (or over a couple of years even). Seriously, that's the only way I managed to find anything about EFI passwords.

Same thing happened to me, if the disk utility and the OS disk don´t work, you have to replace your HD, mine was a Seagate and they told me it was a mechanical failure.
