    Hope someone can help out with this.

    Here are the specs for my mac:

    5 1/2 year old 17 inch
    1.83 GHz intel core duo processor
    2 MB shared L2 cache
    512 MB of DDR2 SDRAM; supports up to 2 GB

    250 gig seagate hard drive

    Slot -loading Super drive (not working, using an external cd drive)

    ATI Radeon X 1600 graphics processor w/ 128 MB of GDDR3 SDRAM
    Built in cam
    Built-in 10/100/1000BASE-T Ethernet (external DSL & cable modem ready)
    Two FireWire 400 ports; three high-speed USB 2.0 ports; two USB 1.1 ports on keyboard
    Built-in AirPort Extreme wireless networking (802.11g)^2

    About a year ago, the hard drive failed, cracked the computer open and replaced the hard drive. No problems up until last night.

    Booted up the computer, had a fan noise that was louder than I ever remember hearing it. Rebooted, noise was still there. Shut the computer down and now it won't even turn on.

    No fan noise, no lights, nothing.

    Anyone else have any idea what the problem may be? Possibly another dead hard drive or maybe dead power supply? Any help would be greatly appreciated. Thanks!

    A hard drive won't cause it to fail to chime.

    The logic board has diagnostic LEDs on it that will give you an idea of what's working. The first LED is the trickle power. The second one means the logic board is on. The third is the graphics card. The fourth is the LCD.

    Definitely not a hard drive, i doubt power supply, but not sure. random question, have you ever cleaned out the fans from the dust?
