Empty the IE cache
The first thing to do when Internet Explorer is misbehaving is empty your Internet Explorer cache. Often the cache is not corrupt or damaged – it is simply too large.
1. Click Tools, then Internet Options, and then click the Delete Files button.
2. A Delete Files window will appear. Select the option to Delete all offline content, and then click OK.
3. Click Settings and reduce the size of your cache to, say, 50 to 100 MB (more if you routinely download very large files).
This will invariably fix the dreaded red x, View, Source, and sometimes "Page cannot be displayed" errors.
