I used to have a netbook (using Windows 7 Starter) and explorer would keep freezing up on me. It always happened when Internet explorer was on. I figured a wanted a more powerful computer anyway so I got a Phenom II 3.0Ghz X4 and 8G Ram with Windows 7 premium.
Then that computer froze several times when I was using internet explorer. Sometimes all I had on were a 2-3 IE windows. So I switched to firefox. And it still freezes.
When it freezes, I turn it off and turn it on again. When that happens and it gets back to the desktop screen, if I ask it to do anything of any substance (like opening firefox/IE, a Jpeg or a Word file) it freezes up again.
I don’t have a great many startup programs. I use both Microsoft windows defender and Avast. What could be causing the freezes?
