I've never used the laptop for a long time. But today, plugged in, turned on, nothing on the screen with 3 long beep and 2 short beep. I suspect the ram would be problematic... This happens for a few times before(but no beep though) and the screen was not lit. Restarted it and back to normal again. But suddenly, the problem happen again. After a restart the screen shows nothing, no beep, the fan spin for a while and stop. That is why I kept the laptop in it's box for a long damn time. I also donated the ram, hdd and power chord.
