STOP THE TABS PLEASE!

Argh! We've been having a few computer issues. . . It is extremely annoying especially when you have things you need to get done requiring the computer. Internet explorer opens hundreds of millions of tabs--everytime I try to go to a new page. STOP THE MADNESS!! IT IS DRIVING ME CRAZY!! If anyone knows how to resolve this. . . please feel free to let me know. I've tried changing the settings in my tools section/internet options. . . but nothing seems to help. For now--I think I won't be around "online" as much--I fear destroying my computer!! :0)
