Check the event log for event 1035 if you have the Dell Support Center still installed (and then uninstall it):

"Every time I reboot, Vista will log an event 1035 for every single app
installed on the PC. So, there are a few dozen entries like this every
time I log in:

Windows Installer reconfigured the product. Product Name: DellSupport.
Product Version: 6.0.3075. Product Language: 1033. Reconfiguration
success or error status: 0."

"Ditto! I uninstalled Dell Support Centre and the problem has gone away."

I disagree with your point that if it had happened in a non christian setting it would have been widely decried. I don't think it had anything to do with religion. IMO, the reason it wasn't publicized as much as Columbine is because *kids* did the shooting in Columbine. People are apparently used to adults shooting and killing, they're just apparently surprised and appalled enough to generate a huge media swirl when children do it.
