Have you installed the latest display drivers ?
Have you tried an update?

I try to update all the drivers !for few days it was perfect but now it ?

Perhaps the driver update is responsible for that...You could uninstall the updated drivers and revert to the previews ones....Did you download the latest drivers manually from your videocard manufacturer or from Windows Update?
