Hi,
Thanks for your post.
You said there are many files were corrupt and missing in the system.
Based on the information, I would suggest you to perform the following
steps:
Step 1
=======
System File Checker:
Please click Start->Run, and then run the following command:
1. "sfc /purgecache" (without the quotation marks)
2. "sfc /scannow" (without the quotation marks)
The system will prompt you to insert the Windows XP CD into CD-ROM.
3. Restart your computer and test to see if the issue is resolved. If not,
please go on to Step 2.
Step 2
=======
System Repair:
- Prerequisite
If your Windows XP is preinstalled by an OEM (Original Equipment
Manufacturer), we need to delete some file first prior to repair XP.
Delete %windir%\system32\undo_guimode.txt
