Hi all and thanks very much for taking the time to look at my thread. I have the following set up ECS 667/1066 mobo/intel 3.4 dual core cpu/2 gig elixer ddr 667 ram/Maxtor 250 gig hdd. I have installed vista premium with no problems at all and when i use the on board graphics everything is as it should be. I put in an ati x1650 pci-ex graphics card and all is still OK before i install the driver that come with the card. As soon as i do install the driver everything is fine except when i shut down i get a BSOD with 2DVAG.dll on the screen. I have visited ati site and downloaded the latest drivers which is in with the catalyst center. When i try to load the latest catalyst i get a message saying cant find installed devices. Has anyone had this happen to them? Or can anyone offer me some advise please??
