What's this mean?

I get these window popups all the time whan i close some programs but not EVERY time. http://[IMG]http://i117.photobucket.com/albums/o79/christopherjellybean/NewBitmapImage.jpg[/IMG] There are some others that say something about memory too but not this same thing. I've done a dell diagnostic test but nothing showed up about memory? Any ideas? Oh and happy thanksgiving!!

Memory errors can be several things ... most commonly the harddrive, the actual ram memory ... or the memory on the processor.

The fastest way to rule out the memory (memory diagnostics are historically not the most accurate) is to swap with known good memory. Do you have any available to swap out?

What type of Dell do you have? Their newest 32 bit diagnostics have a new memory test that is much more accurate ... but I'm not entirely sure how old of a system the new diags will work with.

 

This as far as I read could be a problem caused by Internet explorer7, try to uninstall any updates you have installed lately, or uninstall IE7 all the way and use firfox for sometime and see what happnes
