would be to use IE to download and then install another browser, eg Firefox, Opera, Chrome, Safari, etc.
Then at least you should have a browser that works on these sites.
When that is done and you have ensured the other browser works OK, I would look into your IE's add-ons, (IE > Tools > Manage Add-ons), and see if there are any add-ons that are affecting the way IE is working.
As a test, close IE down and goto Start > All programs > Accessories > System tools and find the "Internet Explorer (No Add-ons)" option and click that. This will open IE in it's Safe Mode. If you can visit those sites now, that shows that some add-on, toolbar, or plugin is causing your problem.
Then you need to find the offending add-on, disable it and if possible delete it.
See if that helps.
