Problems with Suse 7.1

I am having problems with suse 7.1 and was wondering if anyone had seen them before. Yast 1 crashes when setting up the ethernet card. Yast 2 also crashes when trying to set up the ethernet card error writeing to modules.conf /etc/modules.conf is actualy named /etc/modules.conf.- I also have many console warings about missing modules any clues? Thanks
