Exit Visual Studio IDE on ToolBox initialization

I'm working on Visual Studio 2008, the SmartAdapter + Infragistics controls are installed and we have over 50 custom controls. When opening the Visual Studio "Tool Box" Visual Studio freezes completely. After that, I couldn't work. I have to kill the process and reopen it. At the moment, the CPU usage is around 50, using CPU 1 or 2 as I work on the code. How to get rid of this problem. This is a really time consuming process.
