    I know...very generic topic but..

    This machine has been sitting for over a year without a start...yesterday tried to start..machine fires up..nothing to screen ( cinema display) more importantly and no chime...video card fan spins up..

    tried new battery...tried removing 3/4 OWC ram simms..tried NVRAM reset although no keyboard access.

    Still no chime.any input appreciated

    Possible CPU tray or logic board, and it's hard to diagnosis without spare parts to test.

    Get a Snow Leopard disk and try to boot from that.

    what gpu is it?
    what version of osx?

    might be worth doing SMC reset by unplugging the power cord for 15secs +

    then pram reset

    also worth doing a boot holding 'alt' to see if there's a valid boot drive (maybe the HD is dead)

    also is some time's it's something simple is the display cable in correct, try a different video out from the gpu or different display cable if you have a spare.

    edit
    also might be worth pulling out then re-inserting the HD's for luck
