These three items are of very little importance and likely don't relate to the crashing at all.
- The service pack database not being reached is a bug that has been open for quite a while. You can always go to 'Help', 'Check for Updates' in SolidWorks to get the latest release which works perfectly fine.
- This means the program is probably just open. No big deal.
- The toolbox is a database that is best shared among users if there are customization inside of it. This is why it is recommending a shared location like PDM or a network drive. It is not a huge thing if it is left local.
Your crashing probably relates to other things though like what hardware is in the machine and where you are storing/accessing your CAD data from. If you want to post up what the make/mode, CPU, GPU, and OS for the machine are along with whether you are storing the CAD data on a network area we can all take a closer look at it and see if there are areas to improve.
