Nobody can tell you anything without proper system info or other technical details. That aside, why not simply use a different browser? There's plenty of them...
I'm using a PC running Windows 8 and IE 10. My agency's IT department restricts our browser to IE (I don't even have admin rights to delete an icon from my desktop...).
Are you Windows 8.0 or 8.1?
If 8.1 the current browser is IE 11
