So I have been dealing with this problem for a while now. At first everything kept saying Video Driver fail so I assumed the card was failing. Replaced that and now I get BSOD or all my USB devices fail and comp locks up. I attached my dumps for 5 of the most recent ones. I run a Intell 3.0g Dual core, Asus PQ5 mobo, not sure on name of PS but its 400w and 4g or ram those I am sure are GSkill. Old vid card was ATI HD Sapphire 3850. New one is Asus EN 8400GS Silent. Any help would be awesome. Oh I run Vista and do have SP2. I know a few of the dumps may say SP1. Thanks in advance
