You're plugging the hard drive cable in backwards.

Are you getting beeping noises when you try to turn it on? That would mean there are POST errors. Listen to the beeps and find their description below.
You also may want to make sure you have properly jumpered the hard drive. They usually come out of the box with the jumper set on "cable-select", but you may have to make it "master" It can depend on the cable from the motherboard to the drive (and which part of the cable you are plugging into).
(the below is from:
http://www.computer-firstaid.com/bios.html )
POST Beeping Error General Codes
Bad Motherboard - 1 long and 1 short beep
Disk drive related problem / Video card problem - 1 short beep then nothing happens
Bad video card - 1 long and 2 short beeps
Bad power supply - 1) continuous beeps, 2) non-stop short beeps
Bad memory - 3 short beeps
These codes DO vary from one manufacturer to another. Almost all computers list the appropriate codes in the User's manual under technical information or the troubleshooting section, so be sure to check the manual and verify what the codes mean.
If no beeps are heard and no display is on the screen, its most likely the power supply. Check for Keyboard lights or for hard drive/floppy drive lights. If lights come on then power supply is good.
Next, inspect the motherboard for loose components. A loose or missing CPU, BIOS chip, Crystal Oscillator, or Chipset chip will cause the motherboard not to function. If you get lights then it could be one of the I/O cards. Try removing each card one at a time and restarting the computer.

How old is your PC? Is it around the Pentium1-Pentium3 range? I have a pc with this problem, and I think that it's a processor/motherboard problem. How did this problem start? Did it just happen all by itself, or after you had been inside the computer? Hopefully, someone else out there can prove me wrong, because if I'm right, that means you probobaly have to get a new computer.

What is the wattage of the power supply?
