Look in the manual - it tells you what the pattern of blinks means. (Can't remember which is which off hand.)

What the nerd community most often fail to realize is that all features aren't equal. A well implemented and well integrated feature in a convenient interface is worth way more than the same feature implemented crappy, or accessed through a annoying interface.

Good New Everybody thank you

I Unplugged All the Ram & the Graphics Card & took the battery from the Motherboard, left it for a few mins then replaced the Battery, then reset the PMU, then reinstalled new memory & and the old graphics card then restarted the my MAC & it worked fine

Then i did some simple diagnostics to see what the problem was & it was the RAM Faulty or None Apple Im not sure ill have to test the ram in a PC

Big Thank you to all & i Hope this post helps Someone Ells out there
