Visual Studio 2013 Crash When Trying To Connect TFS

Hi,

I have worked with my TFS about 3 months but it is crashing my VS2013PRO now and in my view, it's reason can be trying to connect TFS automatically. I have un-install and re-install VS2013PRO too but it has not fixed. Firstly how can I see it's crash reason? 

Thanks.
