Windows 7: Firefox not responding

I have this new laptop, barely 3 weeks, Sony Vaio, Intel Core i7 CPU Q 740 @ 1.73 GHz, 4GB Memory. Graphics: Nvidia GeForce 310 M. I have updated all the software and drivers. But randonly when I am doing search on the internet, the computer freeze up and Firefox gives me this error message like: Firefox not responding... I cannot do anything on the computer while this error message is on. Can someone help me out. I did some research online and follow the advice on 7 Forems about checking the System Integrity Checker. Everything was fine there, then I did the Start > Event Viewer > Windows Log > Application > Errors. These are the errors I saw - listed below. Can someone please tell me how I can fix these problems and stop my computer from freezing up and run smoothly. Thanks
