dc3 thanks for the welcome.
I tried the sfc/scannow and it told me "Please instert the windows XP professional Service Pack 3 CD into your CD-rom drive."
I google searched sfc/scannow and found this link:http://www.updatexp.com/scannow-sfc.html
I think the problem is that somehow when I installed service pack 3 back in 2008, it somehow don't match with what it needs to match up with for the sfc/scannow to work?
I am researching what to do next. I guess it wouldn't do any good to try the recovery disk that came when we bought the computer back in 2006 which don't have Service Pack 3 on it.
When I click on start then accessories then click system tools then click System Information it says my operating system is "windows xp professional" and the version is listed as a version of service pack 3 but when I get system information by clicking start then "my computer" then "view system information" it says I have "windows xp media center edition" version 2002 service pack 3. I wonder if this would make a difference? I noticed this difference a long time ago but didn't investigate it.
My computer is a Windows XP media center edition so I have always wondered why in some system info it says windows xp professional instead.
Anyway, my internet connection seems ok now. Most of the time all I do on the computer is use the internet so I have time to work on this.
