I just got my computer like 2 days ago, its using windows 7. Its a Toshiba A505-S6980. The problem is I'll be working on the internet then all of a sudden some of the windows will freeze and say not responding. Most of the time it fixes itself and other times it closes all the internet windows. I'm not sure if its a big issue but I'd like to know if I can do anything to make it not do that.

Unfortunately many computers come with a lot of trial programs installed by the computer manufacturer. These programs often slow down the computer and are the cause of many errors. A program called "The PC Decrappifier" may help or you can identify the trial programs and uninstall them manually via "Unistall a program" in the Control Panel.http://www.pcdecrapifier.com/downloadBefore you do this make sure you have created the manufacturers system restore DVDs. You should also back up your computer to DVD or an external hard drive with the Windows bakcup system.Kerry Brown MS-MVP - Windows Desktop Experience

Add to Kerry's suggestion, you also can disable all startup items and third party services when booting. This method will help to determine if this issue is caused by a loading program or service. Please perform the following steps: 1. Click the Start Button type "msconfig" (without quotation marks) in the Start Search box, and then press Enter. Note: If prompted, please click Continue on the User Account Control (UAC) window. 2. Click the "Services" tab, check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray). 3. Click the "Startup" tab, click "Disable All" and click "OK". Then, restart the computer. When the "System Configuration Utility" window appears, please check the "Don't show this message or launch the System Configuration Utility when Windows starts" box and click OK. Please test this issue in the Clean Boot environment, if the issue disappears in the Clean Boot environment, we can use a 50/50 approach to quickly narrow down which entry is causing the issue.
