Windows 7 can't access links on web pages

Hi there

I have a new laptop running windows 7 and IE32bit as well as IE64bit. Using Twitter as an example, but it applies to every web page I go to, with 64bit I can use any tinyurl links (or links in general) but if they take me to, for example, Youtube I can't access anything because flash can't work with 64bit apparently. If I use 32bit none of the links work even though in theory flash will work.

I have tried some of the suggestions in various websites, such as unchecking automatically detect settings and resetting IE but to no avail.....any ideas?
