If you don't know how to replace your drive, it's very simple. Look up a little something called a "service manual" for your model of computer. It includes pictures and text which make servicing the thing a breeze. Back when I was first getting into internal computer repair I used those service manuals all the time, but since then I just do it without one. That is, unless there's a big problem that I don't know how to solve. Once I had this computer that you had to remove the front cover to in order to get the CD drive out and I couldn't get it off. I had to look it up in the service manual and there was a small little release switch in the BACK of the computer. Who'd look there??? :blink: Well, it was easy after that. I wish you the best of luck. Hope it wasn't really a software problem otherwise the new drive won't work either.
