Why Access 2010 keeps crashing

I am using Access2010 (.mdb or .accdb or .accde) application as front end and SQL server 2008 as backend and operating system is Win 7. After sometime, my application stops responding. I get the following message


"Access has stopped working"

I have to restart the application again.
