When i enter safemode and disable the video card windows work normaly. I gaved the card to a friend some days and he had no problems with it. I tooked the newest drivers from asus and ati but no results.

Sometimes new drivers don't work as well with old cards. Try an older driver, get one here: http://downloads.guru3d.com/download.php?id=18

Be sure to clean out your old driver before installing the new one.
