Display Adapter Problems

Windows XP SP2
Nvidia GeForceMX 440 AGP8X
Monitor Samsung SyncMaster 940b

- The problem: Everytime I boot the computer and it loads windows xp,
there's a yellow mark in my Hardware/Device Manager/Display Adapter. No
Monitor icon also.

The temporary solution takes a few steps:
- to disable de display adapter.
- enable the display adapter, and after that the monitor icon magically
shows up.
- click on Control Panel/Display/Settings and it shows 640x480. Adjust it to
1280x1024.
- click on Advanced tab and change the Refresh Rate from 60Hz to 72Hz.

The system works fine until next boot.

I've tried to uninstall the video drivers, install it again, even in safe
mode.
I've tried to uninstall de monitor drivers.
Exchange the video card with other from another computer.
Clean the registry with a video cleaner drivers, and make a new clean
install.
Use the software Registry Mechanic to fix any possible flaw in the windows
registry.
Run sfc /scannow to replace any possible corrupted system dll file.

No success at all, I lost my video configuration every boot, and have the
yellow marked video adapter.

I have to clue how to fix the problem.
I would appreciate any help.

Thanks.
