I ran the repair on both computers and rebooted. The larger computer's icon (Vista, 6 GB RAM, dual core quad CPU) never started spinning. The smaller computer (XP, 2GB RAM, 3.4 ghz CPU, started to spin on boot up, sputtered several times, then stopped. I'm starting to get a bit worried here. If I understand the purpose of the rotation, it would appear that I am un-protected and perhaps even being hacked. Any more suggestions? By the way, I will add the other programs after I figure this one out. THanks for the help.
