General bad performance

Hello to all.
I need some advice here. I work SW in a HP Workstation xw6600 withIntel Xeon CPU E5405 @ 2.00GHz and 4.00GB of RAM and nVidia QuadroFX 1700 (with the latests drivers) in Windows XP Pro 64bit. Igenerally have several performance problems and I cannot focus whatit causes them.
Cause the PCmachine has large RAM, SW never crashes so I can runthe RX and get an idea of what is happening.

Is there any way to see whats going wrong (like a test orsomething)?

P.S. In the SW RX diagnostics everything looks pretty muchokSolidworksAdministration
