I recently installed Windows XP Pro x64 on My AMD sempron computer. Ever since installing the OS when I eject a cd out of the cd-rom and then immediately put in a new cd, the old cd starts up, not the one I just put in. I have to eject the new cd and click on my cd-rom desktop icon, ok the error message and then reinsert the new cd, which now loads. Any suggestions on solving this problem? Thanks.
