Recently installed BT broadband and since have encountered problems. I have re installed system disks, drivers and software.Every 10 mins The computer gives the Nt Auth Error above wnd then restarts

I am a new user and very frustrated please help

Running Xp and Mcafee anti-virus

does your error have more detail? such as:

The system process c:\windows\system32\lsass.exe terminated unexpectedly with status code -1073741819. The system will now shut down and restart. shutdown initiated by nt authority\system.

That error is probably caused by the Sasser Worm. First, enable the Internet Connection Firewall
