Actually, the person had mentioned using the Catalyst control center, so I installed one. Then she removed it because she didn't think that whatever had worked before had to be "installed" - it was always there, right?

She phoned a computer store and he said she needed to install the AMD catalyst control centre (the program she had removed) and gave her download guidelines. Now her second monitor (a CRT televison) and a second set of speakers are working again. DUH.

Thanks for the ideas!
