Repairing Windows after damage is very advanced work. This is why so many have learned that for most of the folk out there just reload the machine with the factory recovery media.
As to our files the moderators all know one line about that and that is "We only lose what we don't backup."
The good news is that by using the factory restore media, most of the time the machine is put back into operation.
I'm a 51 year old computer no-nothing. Here is my problem; Couple of months ago my desktop Compaq Presario SR 2050 NX got a vicious trojan virus. It would no longer reach the internet (my MagicJack home phone system and Skype still worked however). I contacted Norton, but, since it would not conect to the internet it was useless. I use Microsoft Windows XP Media Center Edition 2005. It is advisable for me to purchase a new tower and replace my hard drive. I have neither a great deal of money, or computer expertise.
Thanking whoever in advance,
