    The machine suddenly stopped connecting to the internet; it says limited connectivity and Windows Diagnosis' error message reads," There was a problem connecting to the TPM (security device) on this computer. It is possible that anti-virus or firewall software is blocking the connection. A missing or disabled device driver could also cause this problem. Please refer to the online documentation for more information." I am using McAfee Security Center and this problem occurred out of nowhere. Please help anyone!!!! :confused:
