    You may have a dead power supply, motherboard, or CPU. If you don't have shop level testing equipment the best thing to do is swap out these items (one by one) with known good ones.

    OK, basic troubleshooting techniques. (I'm assumming this is a desktop system and not a laptop.) If you're not comfortable carrying out the steps outlined below, take it somewhere for service. Never force any components or cables. A gentle pull or push is all that should be required.

    Is the system an AT or ATX? An ATX shuts off by itself without having to touch the front panel power switch. To turn off an ATX (without a command such as the windows Shut Down command), press and hold in the front panel power switch. The system should power down in around five or six seconds.

    Remove the case cover.

    Apply power to the system. Are the CPU and power supply cooling fans running? There may also be a case fan, usually located behind the front panel near the bottom of the chassis. They should be spinning quite fast and provide good air flow. Feel around the edges of the CPU heatsink. You should feel a good breeze.

    Turn off the system. If it's an ATX, unplug the power cord from the power supply.

    Look at the power supply. Is there a dust buildup on the fan/grill? (Outside, rear of the system.) Is there dust buildup on the PS intake vents? (Inside the system.) Either blow or vacuum these off as best you can with a vac and upholstery brush attachment. (With the power off of course.)

    Same inspection goes for the CPU fan/heatsink assembly. Don't use a vacuum here. Blow/brush off as much dust as possible. Try to get between the fins on the heatsink. (I use a one inch wide natural bristle (animal hair) paint brush to dust things off. Don't use nylon bristle brushes as they can harbor static charges.)

    Ensure the CMOS chip is fully seated.

    Next pull and reseat your RAM sticks. This helps clean oxidation from the contacts.

    Disconnect all your IDE devices and data cables. (Hard disks, cdroms, cd burners, etc.) This helps diagnosis if one of these are at fault for your problem(s).

    Leave they floppy drive connected. Ensure the power and data cables to it are snug and in the proper orientation. ie; Pin1 to Pin1, at the drive and on the motherboard.

    If components are good the system should boot/POST at this point.

    If it does, start connecting the IDE devices one at a time, again ensuring all your cables (power and data) are secure and in the proper orientation. ie; Pin1 to Pin1, etc.

    If this doesn't help, then one of the three main components are cooked.
