Q: macbook 4.1 has a black screen at start up and no booting sounds
after 6 months of storage due to keyboard flex issues, my macbook 4.1 running exclusively on windows 7( not via bootcamp) would start to a black screen with no booting chime. the screen would have a faint blink, the camera would check (green light) and the LED light at the front would light white and the fan rotates but just for a few seconds. i figured it could be heat problems so i changed the thermal paste and the problem of shutting fown on its self after 5 seconds stopped but the black screen and no booting chime problems persisted. the computer still checks the camera, screen blicks faintly on startup as if doing a startup hardware check, the fan rotates and the LED light is on but no booting and screen is black. what could be the problem, please assist. I have tried resseting PRAM, CMC and even changing the CMOS. i really need assistance.
MacBook, Windows 7, macbook 4.1
