Hi, welcome to TSF.
First ground yourself by touching the back of the case. Then disconnect the computer from the wall and open the case.
Make sure the jumper is set to master and that the drive is connected at the end of the ribbon cable. If there's another device connected to the same cable - make sure it's set to slave.
Check the connections at the drive and at the motherboard and try another power plug to the drive.
Enter BIOS and set all channels to "Auto" - save and exit BIOS.
