I followed Robert Profitt 's last advises and re-installed windows. but I cannot install "Norton Internet security" again because it needs the Win SP 2 or Higher. The problem is that when I try to install the SP2 or SP3 I have always this error message: "the file C:\windows\system32\drivers\ndi.sys is open or in use by another application. close all other application and than clic Retry.
I don't have any other application opened because I have'not installed anything else yet. except the necessary drivers..
Thank you so much if you can help.
