Someone suggested that we would need to start all over with the computer and reinstall all the programs. That's fine. But when I inserted Windows XP cd into the drive nothing happens. The cd player whirrs for a few minutes, then shuts off with no recognition of the what is in the cd. I tried rebooting, at least I think that's how to do it, by leaving the operating cd in the drive, turning off the computer, then turning it on again; however, the option to run computer from the cd never comes up.
The irony of all this is that this happened when I was downloading the new Norton Antivirus. In the middle of the download, a contact help desk popped up, but the link would not work. Before this we have had adware/spyware called Aurora that was always impeding our computer. Whether this was the cause or not I do not know.
So, how do I start over?
