debugging - random error when running the application

Sometimes I run my application, it will show [not responding] and be forced to close. I captured a Dump file and open it in WinDbg. Below is the information I get:

Loading unloaded module list
.
This dump file has an exception of interest stored in it.
The stored exception information can be accessed via .ecxr.
