MacBook pro not starting

[samraat]

Hello PPL,

My MacBook Pro is not booting up. As soon as i press the power button, there is some internal noise (which is common) but the follow up beep sound is not there. The screen is also black. Although the white light blinks.

I have tried all trouble shooting mentioned in http://support.apple.com/kb/ts1365 but nothing is working.

In between it did start once, but when i restarted the same problem is reoccurring.

Can any one help me out.......

Regards
Sam

if you can get the wight screen try pressing alt with you mac disk in and reinstalling osx if not get it repaired or if not under warranty attempt to troubleshoot the problem, ie if you have another mac get it to boot from the faulty ones hard drive to see if it still works to do that just boot in target disk mode
