Problem with the usage of my CPU

Hello there!
Please help me, I am having a problem with the usage of my CPU.
I have this C# Console Application that locks up my Windows 2003 server whenever I try to run it.
I tried quitting the application but the UI was not responding to mouse clicks.
I need to know if there is a way for me to configure the C# Console Application so that it would not take up more than 50% of the CPU usage.
I would also like to know if .NET framework has a global setting that will allow me to monitor the applications so that they do not take over the machine completely.
I hope you can give me the answers I’m looking for.
Thank you very much…
