Did you follow the steps in this Apple note on starting with no video? If yes, and still no video, the last step is take it in to Apple for service.

Hi, thanks for the response. But I my computer don't even give a flash of light on the screen, it just chime, like 2 to 3 second apart. I'll still try some of the stuff on the apple note.

Is it the startup chime, or a periodic beeping? If it beeps like 3 to 5 times, pauses and repeats, along with the power on LED flashing, that's a different issue.

Is the chime, it just repeat it over and over.

- Shut down your Mac.
- Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
- Turn on the computer.
- Press and hold the Command-Option-P-R keys before the gray screen appears.
- Hold the keys down until the computer restarts and you hear the startup sound for the second time.
- Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information.
The above is from this Apple document:

Thanks Eustace for the replay. I have tried that and nothing. Still only does the startup chime 5 seconds apart and nothing more. No video. I remove the RAM and try other sticks and still the same.
