Lisav,

Thank you for using the Dell Community Forum.
You have several options you can try.
1.Run the SFC utility from the other user account.
2.If the other user account has admin rights, deleted the corrupt account, and recreate it.
You'll have to recreate the user settings for that account, and you should also backup any data files for that account.
3.You may want to try a repair install of XP, but be aware this will affect all accounts.

Information:
To try and fix problems with Windows corrupt files, please try using Windows SFC.

Solution:
1.) Put your WindowsXP reinstall CD in the system.
2.) Click Start, Run.

You need to have SP1 ready to reinstall after the repair install.
You should also reinstall the Microsoft updates that you deem necessary.

How do I perform a Repair Reinstall of Microsoft® Windows® XP?

Discussion
Windows XP includes a new reinstall option, the Repair Reinstall. This option should be used when you have determined that the operating system files are corrupt, but you do not want to completely format the hard drive and reinstall the operating system.

What a Repair Reinstall Will Do
Delete all of the files normally installed by Windows XP.
Reinstall those files from the Windows XP CD.

What a Repair Reinstall Will Not Do
Completely rebuild the registry. A Repair Reinstall only writes to parts of the registry used by Windows XP. It will not completely rebuild the registry.
Delete applications and user settings. A Repair Reinstall will generally leave applications and user settings in the state they were before the Repair was attempted. All applications should remain functional, and all user settings should remain the way they were.
Fix issues caused by corrupt applications or user settings. Since the Repair Reinstall does not affect user or application settings, it will not repair issue stemming from those settings being corrupt.
Solution

Performing a Repair Reinstall
1.Insert the Windows XP CD into the CD or DVD drive.
2.Configure your system to boot to the CD drive.
3.Restart the computer.
4.When the computer prompts Press any key to boot from CD, press the (Spacebar).

6.Press the (Enter) key to continue.

8.When the license agreement screen appears, press the (F8) key to accept the license agreement.
9. You should now see: (C:\Windows )
Press F3 to quit, R to repair, ECS not to repair.
You want to press R at this point.
Windows will begin to load some files...asking you to please wait.
10.Setup will proceed with the installation sequence appropriate to the version of Windows XP being repaired.
Once setup is complete, the system will restart.
