Thanks a bunch
...our 'puter is 3 years old and has 244 RAM, what kind of # is that anyway??? I'll see what I can do and get a friend to help!
Your computer has shared video memory. It actually has 256MB of RAM installed and 12 is dedicated to the video processor. It also means that your video processor is part of your motherboard so there's no video memory upgrade possible. Should you want to upgrade your video card, you could change a jumper on the motherboard to turn it off and add one.
You probably have (2)x 128MB RAM modules installed. Depending on how the motherboard is configured, you probably have at least 2 open RAM slots left. If you have two, you'll most likely have to buy two more as that generally means your board accepts them in pairs, although this is not always the case, especially if it takes different types of memory modules also.(long explanation I won't go into here unless necessary)
I would take the previous posters advice and start with a memory upgrade. If you can't determine what you currently have installed in your computer, post the make/model and I might be able to find the specs for the memory that would work in your computer, then you could just remove the old one(s) and replace them. Or just add the extras if you have available slots. Memory is relatively cheap, especially if you have a small computer dealer nearby. Best Buy or CompUsa aren't overly high-priced either. Or crucial.com is another good source.
Photoshop just loves memory, it's one of the few programs that will use all you give it. At a bare minimum, professional photo editors start with 1GB of RAM in their machines.
Cobaltbabe's suggestion is a good one if your PS scratch disk is set to the same drive as your program files are on, otherwise it will have no effect.
