I run a processor not too much faster than what you run (AMD-1800+), but I have 2 GB of DDR Ram. I have LOTS of ram, an over kill mind you, but I run ALOT of things at the same time, sounds like your biggest problem is you need to do what others said and clean up your system..also, you must get more ram. IMO- it is your lack of a sufficient amount of ram causing your problem. I had alot of the same probs before I went over kill on ram. You have to take into account that everything, including your video card may be using your ram if it does not have ram of its own on it, plus windows uses so much and all the other stuff you run. You will get slow downs and freezes when there is not enough ram.
