This AM I had my first Blue Screen - right after booting I clicked to change a background Image and got an odd error 'Page Error in Non Paged' and that was all I got before screen flipped away In the Sytem Event Log I have two critical events 41 The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. and 100: The scheduled diagnostic task detected that the computer maintenance check is in state 0. A: what logfile can I recover the BlueScreen details form? B: might this be related? Code integrity determined that the image hash of a file is not valid. The file could be corrupt due to unauthorized modification or the invalid hash could indicate a potential disk device error. File Name: \Device\HarddiskVolume2\Windows\System32\drivers\adfs.sys My Beta is installed on a machine where I ran diagnotics and testedboth drives integrity before installing. SO- any ideas folks? - TIA - JonB

BSOD events should be available in the System log file of the Windows logs in Event Viewer. If it's not there, there's many different reasons for it not showing up.Then you'll have to look for the memory dump file. There's 2 general places that they're stored. 1 ) In the Windows directory in a vile called MEMORY.DMP; or 2 ) in the Windows\Minidump directory.If you locate the memory dump files, you can use this link to perform an analysis on them. Then post the results of the analysis here for us to have a look at. How to read the small memory dump files that Windows creates for debugging FWIW - this article was written for small dump files in other OS's - but the principles remain the same. For futher assistance, use the Help files in the Windows Debugging Tools. - JohnEDIT: Before you go into all of this, you may want to uninstall your Adobe products to see if that fixes the issue with adfs.sys
