I am using Windows XP. A few days ago when I left home at lunch everything was working fine. When I returned home from work the first thing I noticed was that my sound would not work. Then the computer would not shut down. I had to turn it off manually and when I turned it back on I had the same message that something was missing or corrupt. I ended up having to do a nondestructive restoration. Over the past few days as we try to use programs it will tell us that some components are missing or can't configure or to try to setup where originally installed. I have tried to uninstall and reinstall several things but most of my programs are not even showing up in the add/remove program area. I have successfully reinstalled AOL 8.0 and downloaded a couple of other things that was on my computer but I can't reinstall Word, my Print Shop is not on here to uninstall and it will not let me reinstall. Someone told me to put my Windows XP cd back in and try to install missing components but XP does not come w/a CD if it was preinstalled on your system. Also, all of my font is in italics. I have also tried to restore to earlier point. No luck. Can I download a service pack or something to fix this? Please help. This has been VERY frustrating. I appreciate anything you can tell me.
