Try resetting the drive detection to Auto
How many SATA drives are installed, that computer if I am not mistaken has two sata connections on the motherboard.
If there is ONLY one SATA are you using the first SATA connection.
Is there also an IDE HDD connected.
Is there a CD DVD connected to the secondary IDE channel.
If that is the ONLY IDE now connected, as the original HDD has been replaced by a SATA, then conect the DVD/CD to the primary IDE.
If that does not work and you are sure that all connections to the SATA - PSU connection and motherboard are OK, then I suggest you reset the CMOS - battery and jumper I would think.
