RAM is so cheap right now you really need to grab some. I got 256 for my daughter for $30, just check the ads. Now that DDR is being used the older RAM is dropping. My 400 used to handle Poser 4 just fine, but I had 128 of RAM. You also need to delete your temp files and delete your browser files. Had a guy trying to run Photoshop and couldn't, said he was running out of HD space. He had over 500 megs in his temp internet files alone. You should be able to go into Programs > Accessories and defrag your drive. Marque
