The two examples you give are both https-pages. If that's the common factor (I mean: all http-pages work, no https-pages work) something is wrong with the settings used for https (say SLL and TLS).
Things you can try:
- another browser (you forgot to tell which one you use, but you can choose from Internet Explorer, Firefox and Chrome)
- in IE, reset the settings to default (in Tools>Internet Options>Advanced)
- another user account in Windows
