I had forgot to eject Windows CD from my CD drive. Then, my sister turned on the COMPUTER. She made a mistake and performed part of Windows installation. Now, when I log in my windows I can't see the list of programs in All Programs . Furthermore, the SPEED of my computer has slowed down and it takes a LOT of time to run a Flash program or open the CD Drive. In addition, my computer does not make any VOICE any longer.

I have checked System Restore capability through this link:Start -> accessories -> system tools -> system restore. However, It did not have any effect.

I do not want to remove my Windows and install another one because I have lots of programs on this windows which I need them very much. Please help me.You can try a repair install. Boot to the XP CD and choose the SECOND repair option, allowing XP to install on top of itself (http://www.geekstogo.com/forum/How-to-repair-Windows-XP-t138.html)Not to be the pessimest here but depending on what she did and how long it ran i'd prepare for the inevitibality that all your data and apps could be gone...

This is why we preach good solid backup strategies all the time here...patio is right, you might be better off performing a clean install just to UNDO the damage. or, you try a repair install. your choice.
