This is likely caused by a corrupt cache. Try clearing your cache and temp files folder. In IE8, this is done by Tools > Delete Browsing History > Check Temp Internet Files > Delete

I would also suggest you use a standards-compliant browser such as Google Chrome or Mozilla Firefox. Otherwise, at least upgrade to IE9.
