We need a little more info. Do you hear the startup chime when you turn it on? Does it sound like it's starting up at all?

Hi Marinilila,
Have you find which is your problem? If no and your macbook pro is the previous version (macbook pro all silver), I think it have problem around on the videocard chipset, he need replace the welding or to replace the videocard!!
Hi ddam81
Yes, I've followed all of the troubleshooting steps and nothing happened.
I actually have the silver model and I'm told by several people who had the same that after 5 years the exact same trouble happens out of the blue and the video card has to be replaced.
But I didn't know about the welding: we'll look into that, too, thanks.
See if it will boot on your Leopard install disk....read on. Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.
Then Repair Permissions.
No need to report any Permissions errors........we all get them.

No chimes - Disconnect all peripherals and the power cord, remove the battery. Take a deep breath & count to 60 slowly. Reconnect the power cord and battery and see if the machine starts normally. If it does, you can start connecting all peripherals one at a time.
If this tactic does not work, disconnect the power cord and hold down the Power button for 5 seconds, then reconnect the power adapter and press the Power Button to turn on the computer.
thanks CMCSK but it didn't work at all.
thanks CMCSK, your link gave me the answer regarding my problem: it actually seems to be the very commun and regrettable failure of graphic Nvidia GeForce 8600m gt cards on many Macbook Pros from 2007-2008.

It really ***** that mine failed over 4 years after purchase because that's how long they have been court-ordered to repair for free.
thanks
