my old cd rom drive was not working very well. i think due to too many discs with pb and j on them. purchased a new acer 40x drive. installed the hardware, but what used to be my e drive has totally disappeared from my computer. i receive a prompt that says " there is no cd-rom player attatched to this computer" i have a compaq presario 5030(pentium II 300 mhz) running windows 98. i figured it would recognize the new drive automatically. someone please help. thank you.
