Post a link to a site where you get the error.

Provide a detailed list of the "differences" you see/don't see betwwen the two computers you mentioned.

I get an error right here on this page and NEVER give it a second thought unless I can read something on the site....The error could easily be related to the ads.

But in your case - is the error bad enough to spend hours on trying to resolve it knowing in advance you might not ever resolve it?
