I had the same problem a few years ago with my '95.....

You need to buy a new computer. I don't know why it froze, but it's definitely worth upgrading....

If you have too many tabs open ,the computer doesn't kn ow what to do . It is too busy . so it freezes. when you are finished looking at something . close it out . that will solve having too many tabs open.
