Hi if you can do a power supply you can do a cd-rom. One thing to look for when doing this is the way the cd-rom is configured. On the back of said unit there will be pins most will come as master. You will have to look at the old one and configure it the same on the new one.Once this is done it is a matter of unplugging three different pluggings. One for power supply, the next for sound and the last for mother boad interface. Take your time and make sure to ground your self before reaching in to the puter.:)
CD drive on compaq presario stopped working. Never have replaced one, but have opened box and added RAM several times and removed and installed power supply, so I'm pretty handy. Can I buy a new one at a big box store and be sure of getting the right one? Is the connector the same on all of them so I can just plug it in? Not sure where to begin.
