What antivirus/antispyware/security products do you have on machine? Include any you have
EVER had on this machine including those you uninstalled (they leave remnants behind which
can cause strange issues).
If no joy something maybe blocking it.
Start - All Programs - Accessories - System Tools - IE with no Addons - does this work better?
IE - Tools - Internet Options - Advanced Tab - click Restore then click Reset - Apply / OK
IE - Tools - Internet Options - Security Tab - click reset all zones to default - Apply / OK
Close and restart IE and/or IE with no addons
IE - Tools - Manage Addons (for sure disable SSV2 if it is there, this is no longer needed but Java
still installs it and it causes issues - you ever update Java go back in and disable it again.) Look for
other possible problems.
Windows Defender - Tools - Software Explorer - look for issues with programs that do not look
right. Permitted are usually OK and "not permitted" are not always bad. If in doubt about a program
ask about it here.
Could be a BHO - SpyBHOremover - Free - standalone program, needs no install, download -
unzip and run - not all are bad however some can cause your issue (Toolbars are BHO's). http://securityxploded.com/bhoremover.php
