My friend just got a PC that came w/ XP home edition (i know the forum says pro but i couldnt find anywhere to put this). She asked me to install norton and office for her. after i installed norton (8.0 antivirus) stuff started freezing up. boot up the computer and it will freeze right after starting windows. the cursor still moves and u can click on icons but programs wont launch. not even control panel. i booted up to safe mode and didnt have that problem. i rebooted again in normal mode and it started fine and was actually running for a while but she called me back an hour later to tell me it started locking up again. anybody know why it's doing this?
