What version of IE are you running? Make sure you have the most up to date Internet Explorer, IE8.
Here are a couple of things that you can try:
1. Disable all add-ons. Click the Start button , click All Programs, click Accessories, click System Tools, and then click Internet Explorer (No Add-ons).
If disabling all add-ons solves the problem, you might want to use Add-on Manager to disable all add-ons and then turn on add-ons only as you need them. This will allow you to figure out which add-on is causing the problem.
2. If disabling add-ons doesn't solve the problem, try resetting Internet Explorer back to its default settings. This removes all changes that have been made to Internet Explorer since it was installed, but it does not delete your favorites or feeds.
Open IE. Click the Tools button, and then click Internet Options.
Click the Advanced tab, and then click Reset. Click Reset.
When you are done, click Close, and then click OK. Close Internet Explorer and reopen it for the changes to take effect.
Does that solve your issue?
