The Windows drivers for integrated Intel chips sometimes have problems. Generally you should make sure you have the latest driver version, because graphics chips (of any vendor) are usually shipped with early incomplete drivers.
In your case you certainly prefer to use the dedicated ATI card for 3d tasks like SketchUp. Check the ATI driver settings that it switches to the dedicated card when SketchUp is started.
If you post some identifying information from the crash report: user name, email address, or crash report number, I can look it up in our database to help identify the problem.
Thanks - no its not resolved - I’ve already checked with the windows update drives - will check manufacturers site too - you should be able to find the crash report from my email address on this forum
