I am running Windows 7 Pro (SP1) 64 Bit. When I try to login to the domain I get a Blue Screen of Death. This doesn't happen all the time (maybe once a week or so). I searched for a solution based on the BSOD error and events in the Event Viewer log, but I haven’t been able to determine the cause. I also did a system recovery,mem test and changed the VM settings, but the problem is still occurring. The BSOD error only happens at login. Any ideas? I can post the BSOD error codes if that will help. I don't see any Windows system file associated with the BSOD error. Thanks.
