Inconsistent "Out-of-memory" Errors

Does anyone know why COMSOL 3.5 will not work everytime you run the same simulation on the same PC, but on different days? I've run a simple stress-strain simulation on a 1mm x 1mm x 1um diaphragm with an applied force in the z-direction. It worked the first time I ran it. I try to run it again this morning and I keep getting an out-of-memory error. When I change the coarseness of the mesh I still get an out-of-memory error just further along in the simulation process. The PC I'm using has a 3.2 GHz quad core processor and 4GB of memory, although it's a 32-bit system so Windows is only allocating 3.25 GB. This system should be more than sufficient to run such a simple simulation though. I had the mesh set as extremely coarse and was still getting the error. I'm getting the same issues with my laptop, which is a less powerful computer, but I've run similar simulations in the past on it and now it doesn't seem to want to run them anymore. It's become hit or miss whether COMSOL will actually execute the simulations or not.
