I need some help figuring out which device or driver is causing me to get BSODs. I see reference to keymagic.sys in the attached debug log but I'm not sure if it's saying that is the offending file or not. Would someone with more experience please have a look and advise? Thanks. NOTE: I usually get these BSOD in DirectX games, especially when using Alt + TAB but on occassion it happens outside of them too. I have the latest video drivers and the problem was happening before also with the prior version. This install of XP is only a few weeks old. I have SP2 and all updates installed.
