What can I do? The model grows bigger and bigger. All the constrains are made against one main piece. Now it takes more than a minute for inventor to process any change to the model.
I am running a dual core toshiba with 4 gigs of ram. How can I make Inventor run faster?

You can use the Demote command, but since you have constrained all of your components to one part, you will lose the constraints.
Sub-assemblies are nothing more than assemblies that are used in other assemblies. Take a group of parts that relate (are constrained) to each other, and start a new assembly that contains only those parts. Constrain them together how you want to use them in your main assembly. Delete those parts from the main assembly, and replace them with the sub-assembly you created.
At the company I work at, we try not to use any more than 30 parts in sub-assembly, and try to make those "bench buildable", meaning that the sub-assembly should be able to be assembled on its own on the workbench, and carried as a single piece to where the main assembly is being assembled, and bolted on there. (Granted, we use the term "carried" lightly, as some sub-assemblies need to be carried with a fork truck, due to their weight.) This also helps in detailing assemblies, as things normally don't tend to get too large to get a good look at them on a B sized detail sheet.
If your selected sub-assemblies are too large, you can use sub-assemblies in those as well.
The main assembly is the parent assembly, and the sub-assembly is the child.
Looks like shrinkwrap is the way.
Otherwise I make some things invisible, Things that wouldn't cause me to draw a part that would geometrically interfere with them.
Thank you.
Your models should follow real world/production processes. If you make subassemblies in production..Your models should match the workflows..Phantom subassemblies are an option too depending on your workflows..
You can also do the 3G switch if you haven't already (assuming you are on a 32 bit OS).. Google will give you tons of info on the 3g switch and how to enable it..
A 64 bit OS and more RAM is also one of the best things you can do when 32 bit just ain't cutting it anymore.

Is shrinkwrap what you refer to as demote?
Demote is ONE way to create a sub-assembly.
This is typically done if you didn't follow logical sub-assembly sequences (as described in this thread) from the start.
Demote simply means you create an assembly within an assembly (sub-assembly) and move desired parts into that sub-assembly.
Shrinkwrap is a different way to do this in that you can also simplify and reduce a lot of parts (or subassemblies) to one part and temporarily replace all of that complex geometry in your assembly with one simple composite body. This greatly speads things up. You can toggle back and forth between the simplified shrinkwrap representation and the full assembly as needed.
Of course you should be using logical subassemblies.
You should also look into using shrinkwrap.
If your system is a 64 bit with only 4Gb of memory, add more memory. A 64b system with only 4Gb is like a 32 bit system with just under 3Gb of memory.
Assemblies and Sub-Assemblies: think of a car as your Assembly, the engine is a sub-assembly, the transmition is a sub-assembly. The tire & rim are a sub-assembly.
This is much nicer down the way when you are doing your BOM in drawings.
Yes RAM is cheap... Add more and get some speed back.

now everything is fine
Today it is (sorta/maybe?!?!?) but what about tomorrow?
Get the extra memory. You wont regret it.
I am a student,
I don't need extra memory I just want to get by. Maybe when I start working.
