i bought new sapphire 6670 2 gb ddr3 and i installed it physically then after installing the drivers which came with it...then i restarted the system and one blue screen appears and the system reboots several times and do not start pls help
Ok I would boot into safe mode press F8 just before the bios hands over to Windows boot loader you will get several options choose boot with VGA drivers that will bypass the ATI drivers. After your systems boots uninstall the ATI drivers. Then download the latest drivers from AMD at http://www.amd.com/us/Pages/AMDHomePage.aspx. The drivers that come with the cards are usually outdated by the time you get the card. Install the drivers you downloaded and go from there. Let us know if that fixes your problem.
