pitter, two places to try for possible solutions to your problem are
www.browsertune.com and
www.pcpitstop.com
Both are free, load no spyware on your machine, and point you toward tweaks and fixes that could well be of help. Be aware; both sites cause problems with some antivirus and some firewall software. If you have to disable something to use either or both of the websites, remember to reactivate everything when you're done. Also, both sites use ActiveX, and depending on your own browser security settings might trigger security alert popups. Both sites warn of these issues, and tell you how to work around them. Be sure to read and understand all instructions, and before you visit either, set a restore point or back up your registry. All tweaks and fixes they offer have "Un do" functions, but be safe, be sure. Oh, and clear your cache, history and cookies first, too
(edited ... to correctly address the questioner ... I really gotta pay attention to "Preview" before I submit.)
