Recently I bought some extra memory for my computer after some req problems with XP (my computer shipped with the min. memory for XP minus some shared vid. memory so it wasn't working too good). I bought a 256mb module at PC133 and everything was fine for the most part after that. Then, recently I started having some problems with the memory. It wasn't really a problem with the actual memory but more with the stuff that was using it. When I first installed it there was always about 120mb of free PM (according to Norton System Doc), but then it started to drop to around 70mb and my computer started getting kinda laggy and choppy. Also the Norton System Doc window would open really slowly and sometimes I would close erroneusly. This didn't happen before and I don't know what exactly is causing it, so any suggestions or info is happily received.
