    Basis; Are you sure your CPU is compatible with your Mobo? What mobo do you have?

    Have you put your CPU you in correctly? Corner to corner, pin locked down?

    Wiring issues; If you plug a fan (case or CPU) into the mobo AND into the PSU pin your PC won't turn on.

    Are you 100% sure you've wired everything correctly? As long as your CPU is compatible with your mobo, there should be no problem. Check all the case headers and fan headers on the motherboard with the manual, make sure they're all right. Even the reset button being the wrong way around could cause it not to turn on.

    We really need the complete specs for the computer so that we can help you.
  5. Did you install the power supply to the motherboard correctly? I think there are two wires, a large one and then a smaller one that is specifically for the CPU. It won't run unless both are plugged in.
  6. you killed the hard drive....the smoking was a dead short in your system. the power supply for safty wont power the sytem on with a dead short. if your hard drive smelled burnt..your going to have to replace it. also look at the sata power plug on the power supply if it melted too then your going to have to replace that cable or the power supply.
    hard drive should not smoke unless you forced the power cable on..bent one of the pins on the drive or drilled a screw into the hard drive pcb or the hard drive pcb is tuching metal.
