I recently removed my CPU fan, cleaned it and reconnected everything.
I now get windows security errors for nearly every site (including Microsoft)
Itunes cannot download updates "the IPhone update server cannot be contacted"
I cannot go to the Itunes Store "Itunes cannot verify a secure connection with the Itunes Store (-9815)"
Websites I can always access (Like Arena Net) give me the bad security cert message and I have to red-shield click through.
I cannot turn on Home Sharing in Itunes.
I have another computer connected to the Router that is having no issues.
My System clock reset to 2008 (I just fixed this)
