Well , if you remember from my post ( " Leadtek Geforce4MX 440 driver problem " - on Driver sheet ) I had major problems after upgrading to this card . Tested all kind of driver but nothing .. So I've took a look in BIOS , in this way maybe I could change somethin' and I've saw the terrible : AGP was selected to 2x . I've changed it to 4x ( this is normal , am I right ? ) but my computer wouldn't even start ( black screen , cooler working ) . Reset BIOS and all came to normal . Now my intention is to change my actual mobo (KT266) ECS M830 Sis 735 ( that is not working with 4x ) with a new one (KT333) : I have 3 choises in my mind : 1) Asus that supports AGP 4x 2) Epox that supports AGP 4x 3) MSI that supports AGP 4x or any else . The definition of the new mobo must include : - stability - performant - DDR memory or SDR with DDR ( both ) Huge thanks for all your help !
