Hi all,


I've been busy with this problem for some days now:


Solidworks 2011 used to work fine until a couple of days ago. When opening an existing part (and solidworks) the program hung. After trying a couple of times I managed to open a new part. Afterwords I worked for something like 4 hours in SW without problems.

The next day when trying to open a part the same problem occured: the program hangs. It is using 100% cpu (1 of my 4 cores), the memory stays the same.

I am able to open a 2D drawing and the basic program without opening a part or assembly.

After looking on the internet, I tried to thick on: "Use software OpenGl". After which I am able to use the program, but much more slowely. I tried the following:


- Updating video drivers to latest (clean installes)

- going back to previous working drivers

- repaired solidworks

- reinstalled solidworks


The problem persist. I can't use SW anymore without Soft OpenGl.


My system:


Intel Q6600 (2.4Ghz)

4*1Gb pc 8500

POV Nvidia GTX 460 SSE2 1 Gb

Asus P5Q-D Turbo

lots of hdd's etc...


OS: Windows Server 2008 R2 x64 with all updates

SW: Solidworks 2011 x64 SDK Sp 2

I installed "OpenGL Extension Viewer" . My OpenGL versions is 4.2. I did some rendering test with that.  No problems there.

So I'm puzzled. I did not install any new software or updates when the problem started to occur at first. First time it occured i managed to work around it by opening a new part. Any help would be appreciated.
