my pf usage is constantly at 236. and i only have 256mb of ram. and i think this is causing my computer to be slow. why would my ph usage be high when i'm not doing so much and the harddrive light is usally blinking as if the harddrive is being used. what could cause this besides spam/spy ware ect. cause i've ran spy bot, ad aware, spy blaster, to clear those things but the computer still runs slow. so can someone explain to me what might be going on? thank you
