If your Internet Explorer web-browsing experience is excruciatingly slow and buggy, in spite of the fact that you are connecting through a high-speed Internet connection on an extremely fast computer, then it may be time for some serious Internet Explorer repair.
If Internet Explorer is constantly “hourglassing”, then it may be an indication of a problem with your Windows registry. Typically, if you are already running antivirus and antispyware software on your PC, and you are still experiencing this problem, then you can rule both of these out. The next logical thing to check is the registry.
