COD wont except the 2nd install CD, but hangs instead

I am trying to install COD the first CD installs fine when the prompt asks for the 2nd I out it in the drive and it does not register, it just hangs or I hit ‘OK’ and the prompt just continually reappears. I am using a Compaq EVO N1000c, I hae tried this on 2 different PC’s with the same problem and 2 different copies (originals) of COD. I did manage to install it successfully on a desktop PC only to have it crash when trying to play it, some VB error…

Any help on the compaq would be appreciated.
