I run Windows XP Media Edition on an HP Pavillion a1250n. I have several problems which have led me to try to restore to an earlier point. These include an error message which says "The TCP/IP Netword transport is not installed", I cannot reinstall my Antivirus software, and a Windows Explorer window showing the folder C:\Program Files\Dell pops up after each reboot. This folder has only one item in it, namely the folder "SystemProfiler", which only has one item in it, namely the file "WMIIinput.xml".
I cannot even get on the www. I am accessing this site via my notebook.
What can I do?
