Here is what happened:

Installed new hard drive and ram upgrade.

Hit power button. (Nothing on the display or keyboard turned on.)

Heard the optical drive turn on every few seconds. 

Held down the power button until it turned back off.

Installed the old hard drive and ram so everything I did was reversed like I did nothing at all.

Pressed power button.

Heard optical drive turn on (no chime noise-just the drive.)

Still no display on (it remains black.)

Tried resetting the smc. No changes.

Tried to attempt a pram reset. Nothing.

Battery shows full charge. Charger shows green light when plugged into computer.


Idk what I could have done or not done to make this happen.
