Have you noticed any signs of overheating in the machine? When automatically the computer shuts down, does the Windows Logging Off message comes or it becomes non-functional suddenly?

Recently I've installed Autodesk 3D studio max, but I have some problems with the viewports - it's lagging.. This is a video, which describes the problem very good - http://www.youtube.com/watch?v=09EaaIF-raQ ( it's not mine ).

I regret for the inconvenience caused, please provide me the system service tag or the express code of the system and let me check what best I can be done. Please reply if you have any further questions. Thanks & Regards Prateek K #iworkfordell
