When started up computer not everything will load!! No taskbar functions, no internet , no start menu etc. In task mangager processes one of the scvhost processes is using 100% system resources. System restore not working: Winsta.dll file-entry point not found. Starting in safe mode system restore still isnt working.Have re-installed xp disc with no luck.. Ran nortons antivirus and nothing. Any ideas besides wiping clean and reinstalling xp ???
