do what bob has said and see
I use 3 programs at the same time to browse,open and work on Nikon NEF (RAW ) files, there about 30 mb each. I have a 1.8 P4 processor and 1 gig of ram, after I open several photos my computer starts to slow down and I need to shut off the programs and open them again to free up some RAM. I saw a program call Turbo Memory that suppose to make your computer free up ram faster, has anyone ever used such a program and do they really work. Thanks
