If the problem is the focus is being changed from your working window to the cap lock icon, you can perform the follow edit to the registry.

Fix the Cap Lock Stealing the Focus issue

When you press the Cap Lock key, it steals the focus away from your active document/window.
Here's how to fix it.

1. Click on Start and then Run.
2. In the text box in the Run window, type regedit and click OK. This will open the Registry Editor program.
3. Locate the HKEY_CURRENT_USER folder under My Computer and click on the (+) sign next the folder name to expand the folder.
4. Continue to expand folders until you reach the HKEY_CURRENT_USER\Control Panel registry key.
5. Select the Desktop key under Control Panel.
6. On the right-hand side of the screen, locate and double-click on the ForegroundLockTimeout DWORD.
7. In the Edit DWORD Value window that appears, set the Value data: field to 30d40. 
   
   Note: Make sure the Base option is set to Hexadecimal when entering the DWORD value.
8. Click OK and then close Registry Editor.
9. Reboot your PC for the changes you made to take effect.

From this point forward, programs should no longer steal the focus from the window that you're currently working in.

Anyone?

You wrote in your first post that the problem happened about 2 days ago - why not just trying a Windows System Restore?

No... Is there any other solution?

What do you mean with "No" ?

Did you run  Windows  "built-in system restore utility" ? I hope that you didn't confuse it with Dell's system restore.....

Assuming you run windows system restore try msconfig.exe and disable some start up items and see if it helps.
