IE8- hang if not used for like 30mins

[happieshortie]

Hi. I just bought my laptop last week. Im using IE8 and have experienced thrice already that my laptop would hang like forever if its left idle for about 20-30mins. It says "not responding" already. I am really worried because Im confused if the problem is with my new laptop or with the I itself. I had to take out my battery just to turn it off because it really is not responding. I tried to show my task manager so I could end it, but even the task manager wont show. Please please help because Im really worried. Im thinking of returned my laptop for replacement, or is it the browser that's the problem?

CPU: AMD dual core E-350
RAM: 2GB
OS: Windows 7 sarter
SONY VPCYB15AG

Or is the problem my OS? should I upgrade it? Im confused if the problem is with my laptop, or the IE itself or my OS

Check that you are using "high performance" under "power options" as a test. Also, does it only hang when using IE? See if it hangs with IE closed and running another program or two.
