I have a compaq Presario SR 1230Nx with 512 mb ddr-333 pc2700 ram. I was thinking about going up with ram to speed the machine up. Will that help?? Or does anyone have any suggestions that will help me. I have the Windows defender that eats machine time. I could probably get rid of that to speed things up. I am on Comcast so I have the McAffe. I am not sure if I need both. I guess that is another question I have?? Thanks for any help you all can give me.
