I've been experiencing 3b bugchecks randomly for quite some time. My machine is relatively new with the latest video drivers from Windows update. I've put the last 4 minidumps in the public folder of my skydrive. Can someone help?? Here's the link: https://skydrive.live.com/?cid=2e05d0f25eb909d1#!/?cid=2E05D0F25EB909D1&id=2E05D0F25EB909D1%21108 Thanks
