What did you try? Did you reset IE8: Tools/Internet Options/Advanced/Reset?...I have tried alot of fixes and nothing works...
The only negative that is unavoidable is the removal of a few addons, like Flash or Java, but since they are a suspected cause of the problem, it's better to add them back later after you've resolved the problem. As you do the reset, a screen will appear explaining what the reset does and giving you the option to avoid changing "Personal Settings" and those personal settings are spelled out. Regardless, you can't loose your personal folders like Favorites, Docs, Pictures, etc. even if you choose to reset "Personal Settings"....but resetting IE are there any nagatives to doing that...
Bing is just another website, different than google, so I would not expect that to make much difference, unless the only time you have browser problems is with google. I suppose their new annoying popup pictures of web pages could be taxing your system a little more....I might start with Bing first and then see what happns...
