My parts turning to black colour whenever i open critical assemblies(heavy files).refer the attachement & tell me the reason.
Often caused by using unsuitable video card and/or driver. Could also be low system resources.
Post your full system specs for review.
Are you using the Large Assembly settings?
Can you post the assy stats?
My system specifications are below,
OS - MS Windows XP
Processor - Intel core Quad
Ram - 3.24 GB
Graphics - NVIDIA
What specific model of Nvidia graphics card do you have? What specific make and model of workstation?
Your issue is most likely video card related.
Do you have an approved video card driver for your workstation, video card and version of SW you are using?
