Last Thursday we started to see a few of our laptops bsod after a reboot, prior to logon. Friday we had a few more and Monday even more. I have found that disabling NOD makes the bsod's stop and then a full uninstall and reinstall of NOD takes care of the issue. This happened to both our Toshiba laptops and our Lenovo's, and didn't touch a single desktop. Was there a bad signature file that came out on Thursday that could be causing this and has anyone else experienced this issue? We actually currently still have one laptop that will bsod, every time NOD is reinstalled to it. Any ideas? Thanks.
