I am getting the following. How do I get repaired? The message is the following:The instruction at "0x01dff020" referenced memory at '0x00000ba0" The memory could not be read. Click on ok to terminate the program.

Those are referring to a problem in the program you were running. They don't indicate any problem with your computer unless this happens in multiple programs. In that case you may have a bad memory module.

It happens nearly every time. This just started after the geek squad at best buy had to restore my computer. They tried to remove Norton's to replace with another and all hell broke loose on my computer. My wife likes to play solitare on bell south and now it will not load either. Needless to say, I am not happy about these problems. After I get back next week I will  pay another visit to Best Buy.

Norton provides a free removal tool that you can download from their web site that does an excellent job of completely removing it from the computer.

I would say the reason you are getting all the error messages is that Norton is only partially uninstalled.
I have heard a lot about the geek squad. The main thing being that they are hired as salesmen, not for their knowledge of computers.
