MacBook doesn't boot, no chime, blank screen

본문:

Hi and thanks in advance for any suggestions/advice.

I have an early 2008 white MacBook 2.1 GHz Core 2 Duo with 4GB RAM 120GB HD, upgraded to superdrive, running OSX Lion.

Two nights ago, I woke my machine from sleep late at night to print a document. Once printed, I put it back to sleep and went to sleep myself. I forgot to plug it in, so the battery died overnight. When I got home yesterday and tried to use it, it would not boot after reasonable time to charge. I unplugged it, pulled the battery, held the power button for a few seconds, and it booted fine. Used it for the night, and put it to sleep.

This morning, I was woken by the fan in my MacBook spinning full-speed constantly. I did not have time to troubleshoot, so I just held the power button to shut it down after it refused to wake from sleep. When I got home today, it would not boot at all.

I have reseated the RAM, tried other RAM I have on hand, followed every guide I have found to "reset" various components, etc. When I boot it without RAM, it does make the error sound. With RAM, the screen flickers for a split second, and then goes blank with the white LED holding a constant brightness. The dvd drive also audibly starts up, you can hear it cycling.

I hooked my HD to a Windows machine and was able to read the bootcamp partition, so I assume the drive is okay, but I do not have another Mac to read the other partition.

I obviously suspect the logic board is at fault, though I am confused by the no-RAM error sound and the DVD drive cycling. Any suggestions are appreciated, the computer is only worth $400 to me so if it comes to the logic board I may have to sell the machine for parts and scrounge for an upgrade.
