We have currently upgraded SW2011 to SP4. The troubled machine is running is a Dell Precision 380, XP Pro (32), 4GB RAM, w/ NVIDIA FX3450. Since the upgrade, it has experienced several crashes/lockups during part insertion (assemblies of 100 to 150 parts), dimensioning drawings and Solidworks Explorer takes an incredible amount of time to load. To eliminate any other issues, Solidworks is the only program running other than necessary Windows processes.
Realizing the provided information is vague at best, I am curious if others have experienced troubles with SP4. Additionally, I am wondering if it may be beneficial to revert back to SP3 and if there is a recommended post on this.
