Problem :
Whenever I browse the internet, through Firefox or IE, the browser eventually freezes on Windows 7 . This happens about every 10 minutes. After the browser freezes it spreads to the rest of the system. The keyboard and mouse eventually stop responding and a hard reset becomes necessary.
Solution :
Internet Explorer 8 loads a bunch of add-ons with it. These, to some extent, also affect any browser you are using, so, for example, Firefox windows were freezing as well as IE8, but to a lesser extent.
Go into "tools" in your IE8 browser window, then "manage add-ons", then disable the add-ons.
I should have done it one at a time and tested after each one.
Instead, I disabled them all at once.
I noticed almost immediately that the internet windows were no longer freezing up.
I started to "enable" them one at a time, but as soon as I got to "Shockwave Flash 9.1.01", the windows froze again.
After hard booting, most of the add-ons disappeared from the list.
Right now I only have some Microsoft and Google add-ons enabled, but IE8 has been behaving itself and is actually pretty zippy.
The windows seem a little clearer than Firefox. Don't know what I have messed up by getting rid of all the add-ons, but at this point I don't care.
When I run into something that does not work, I will download add-ons one at a time. Hope this helps someone.
