Slow opening Solidworks models on Precision Workstation 360

About 3 months ago I purchased a new Precision Workstation 360 with 3.0 gig Intel CPU, 80 GB HDD, 1 GB RAM and a nVidia Quadro FX 500 graphics card. We are running Windows XP Pro SP1. The drive has about 73 GB free.

 

We use a 3d mechanical design program called Solidworks 2005. The system as configured above far exceeds the minimum configuration for the Solidworks software. The models we are working with are very small both in number of parts involved and total size of data.

 

The problem we are running into is that when we open an assembly model it takes almost 3 minutes for the model to open. We watch the CPU usage in Task Manager and see that most of the time the system is idle. A part file loads and then is sits idle for a several seconds before the next part file loads. The files are loading from the local hard drive.

 

We are having this issue on two identically configured workstations. We have tried disabling our Symantec Enterprise Anti-virus software, disabling hyper-threading, ran a scan disk and drafrag, installed Diskkeeper to prevent the drive from becoming fragmented. We have also added a second hard drive and set the virtual memory to use that drive for the page file. We increased the page file to the maximum 4GB size.

 

Any suggestions as to what else we can do to improve the loading time of these files would be greatly appreciated.
