I am also having the same problem I can't download anything from I tunes to Norton or Ad Aware and also can't update to a newer version of any program. Some downloads stop at 90% with an error message and some never begin, I have tried everything I can think of any help would be much appreciated. Its so bad you will be lucky if you can load a 60 second video on youtube. I have found that sometimes you can save a file you are trying to download to an external drive and then open it and run it from that external drive to install on the computer but a lot of downloads wont allow you to do this it automatically attempts to update or download files through internet explorer by default and sometimes you can't change this. Cpu is up and running fine just cant do much with it internet wise. Thank you for any further assistance.
