My computer is screwed.

I don't know what is wrong with my computer. Everytime I click on something I have bookmark I have to refresh the page. I figured this out last night. I was browsing through the blogs I read, and no one had updated since like Wednesday, I thought this is crazy I know people are updating. So now I have to caught up on everyone's news. It is just the blogs that are not refreshing, the newspaper, and some other things are fine. I will have to figure out this little problem. So if you have not seen my commenting it is because I thought you were not writing.
