I have a theory. When you removed your old drives, first by uninstalling them, you shut down the computer but didnt restart it, windows never had a chance to "recognize hardware changes". Also, i believe windows is still assigning the old drives drives letters to those devices, even tho they are not physically there. Those drive letters are not usable by the new drives.
so given all that, i think what you should do is:
Turn off machine, remove all new drives.
Turn machine back on and see what it says as far as cd/dvd drives. After you assess that..
Turn off machine and install one drive.
Turn it on, see what it says about that drive in BIOS, if its recognized properly...then continue to windows, and have it recognize new hardware and autoinstall drivers. You should mannually assign a drive letter to it, like "M" or one far away from the beginning of the alphabet so your computer cant have conflicts.
If/when that is all done and working properly, turn off computer and repeat steps for the new drive. If it doesnt work with both, take the other out and see if it recognizes it.
Have you checked the SATA cables and ports on mobo for damage?
