Well, now everything is better. If anybody has my problem, he has to change the settings to 'notify, but don't download or install'. Check for updates, and then choose to view available updates. There you must choose what you see about graphic cards.
It´s not the 9600m gt drivers
But it´s better than before:
The only problem is that my graphic card can reach better. In windows vista, the "gaming graphics" was 5,9. But yet I can´t install its drivers. Anybody knows what can I do now?
(I think I am going to try with Windows 7 64 bits now)
Thank you!!! A very lot!!!
