...don't necessarily mean they were "placed" on the computer at that time, but simply that they were originally "Created" at that time. Many driver and system files have dates from when they were originally created and that's the way they are supposed to be. As an example, I just checked a brand new Windows XP SP2 HP laptop and some of the .dll files in the C\Windows\System32 folder were created in 2003..

It would sure help to know the operating system of the computer in question.

Hope this helps.
