It just happend a week ago... Internet became terribly slow, many websites - about 50% of them - don't load at all (page not found), and I can't send Email - only recieve. MSN Messenger either connects or not, it depends if it feels like doing so :\ In addition, Start->Run->cmd->ipconfig had displayed: "ipconfig" is not recognized as an external or internal command, and something with a batch file. I was fixed by going to My Computer->Properties->Advanced->Enviroment Variables->Path and editing it to c:\windows\system32. Before changing, it had been something with Quicktime, which was fully uninstalled afterwards. My Specs: AMD X2 4400 7800GTX Extreme 256MB DFI LanParty Ultra-D OCZ 1GB (2X512) 2-2-2-5 WD 250GB 7200RPM ENERMAX 485 Watt 3DMark 06 4703 Using: NOD32 Sygate Firewall Adaware Regvac Registry Mechanic Tuneup Utilities 2007 Whats the problem? I've tried uninstalling the Ethernet drivers and reinstalling, didn't work. My computer is virus and spyware-free and well-protected. What could go wrong?
