Keep getting "New Hardware Found" at startup

I'm working on an older PIII machine that lacked an ethernet card so I put the card in and then tried to install the drivers at startup, after the machine detected it. Well, that did not work so well so I reran the installation program and uninstalled the drivers, uninstalled the card from Device Manager, turned the machine off, removed the card, rebooted, reinstalled the driver program, turned the machine off, put the card back in, rebooted, and after a few tries, the machine recognized the card and it worked from there. But now, I keep getting 2 "New Hardware Found" windows at startup. One shows a PCI Device and the second one shows up for Ethernet Device. I cancel both and checked Device Manager which shows no yellow question mark devices or any devices installed with a yellow exclamation point. As far is it looks to me, everything is installed properly but I keep getting these pesky windows coming up at every boot. How do I correct this? The machine in question is running Windows ME with all of the latest updates currently available. Also, Norton Anything is NOT installed on this machine. In fact, there really isn't much of anything installed except the OS and a few applications like Works.

ps, I can now truly appreciate XP.
