I deleted some files on my computer and installed Office 2007. Now I get files that are numbers and letters all over the place. When I try to get into any exe program it says that "windows cannot open this file: rundll.exe or fstrui.exe, etc.. etc.. Then it says to "Use the Web or Select from the program list".I can get online but whenever I try to download it says it is an unknown file and when I "select from a list" it takes me to that program... but doesn't load. I am frustrated. Short of tossing the computer, I am at wits end. On startup it loads windows properly. I wanted to restore, but I was getting messages as above and unable to restore from CD. H-E-L-P...
