My internet was acting up unlike it usually does, and in an attempt to get it back to normal, I shut down and restarted my laptop. When I shut it down, vista installed an update. When I turned it back on, not only was the internet (wireless or otherwise) unavailable, but the Security Center was not running, and my audio service was offline. I found a method that was supposed to fix the security center problem. I set the startup type back from disabled to automatic, but when I click 'start' I get "Windows could not start the Security Center service on Local Computer. Error 1068: The dependency service or group failed to start." I get the same error message with my network connections. I'm using my desktop right now.
Edit: Just tried to run System Restore, and I was unable to. Also tried to back up my hard drive, this won't run either. What is going on???
