I inserted a CD from a client. The computer started blinking. I lost the finder, though my docking station is visible and I can use programs. I put the CD into another computer and same thing happened. Now both have same symtoms. They both blink, the hard drive icon is missing as well as menus. I was able to get to sysmtem prefs, created new user, went to ultilies and check harddrive but I that did not help when I went back to my original blinking user. Did the CD contain a virus? How can I get my finder back.
