thanks for the great suggestions guys.
i've done several things recommended.
i've created different user profiles (well, actually one. and that's mine and it's got a password on it).
i am the only person that use this computer now. my parents and lil bro uses the older 500mhz k6-2 pc.
my mom is the only person that occasionaly gets on anymore (when the other pc is busy) and she doesnt know to go much further than check the history (i forget it sometimes, but i've been lucky so far). i put a porn in a remote location and she wont get 1000 miles from it.
i've also burned a lot of cd's (i'd say about 25 cd's) and i still got about the same amt on the hd. the cause?? one word.
