Solidworks hangs, seems to kill Win Explorer?

Question asked by 1-SALGJC on Aug 5, 2010

I am a contract engineer and during the day I work on-site at a company using a Dell Precision 690. It is not a great machine but it is not a total slacker either. I am under the gun on a really tight project and I cannot afford this kind of mysterious issue.


So, Solidworks 2010 SP3.1 frequently seems to hang when I am opening an assembly. The assemblies I am working with are growing in size as they develop but  are not very large yet (11-12MB). As they grow the problem seems to happen more  often. It is not one certain file but only seems to happen when I have other SW files open already. When it happens all the icons on my Win XP desktop disappear (which indicates Win Explorer crashed). Any iconified app I open shows up but when I try to close it it persists on the screen. If I move the task manager around on the screen it leaves a trail of it's image across the desktop. These last two items tell me the OS is having issues but the resouces being used are very low. I tried to kill some of the processes that were not system critical and the machine is just not coming back. I have to shutdown and restart (hard shutdown, reset will not respond).


Also, with this machine I have to shutdown and restart several times a day to prevent even more of these problems. It seems like the longer I have SolidWorks open the more likely it will hang up.


When I check task manager the performance of the processor is low at 3-6%. The memory usage is not unusual and I have free memory available. If I look at the processes, SolidWorks.exe is not using a large amount of resources (say 200-300MB of memory) but it isn't changing, just stuck at one number. This indicates to me that SolidWorks is somehow stuck, but I don;t know why.


This problem has been persistant and the IT department actually rebuilt the machine and did a complete fresh install of the OS about 2 months ago. Now our IT folks have washed their hands of it and will not respond to any new tickets but management will not replace the machine either. I am going to send this to the VAR as well but my past experience is not so good there either.

Anyone have an idea of what may be happening?
