You don't say whay operating system you have or what software your trying to install. Post back with that info if your still having a problem.
One thing I would try is setting the CD-rom as master and the CDRW as slave. If the computer can still boot up to the OS before locking up then the "readings" for the hard drive are OK. (Some BIOS don't display any information for the hard drive once you set them to "auto".) But if the problem occurs after the BIOs information is displayed make sure you
didn't dislodge the hard drive's cables when you installed the new cdrw. Check them and the power cables to your hard drive(s).
One other thing to check: The IDE cables have a red line on one side that should face the power connection and in turn the power cable's red wire should also face the red line on the IDE cable.
Good luck
