  1. I have had more BSOD’s this year on my laptop than in the past 10! Usually Ndu.sys which, apparently is up to date. As well as KMODE EXCEPTION ERROR HANDLING or something like that.
    Quite frankly, if I could get all my apps and games to work on Android, I’d happily quit this Micros**t rubbish on my laptop and two desktops.

  2. Mine seems to be shutting down at about midnight but not every night. I have a backup program set to run at 1215 AM and my computer shuts down before that starts up. Not every night but often enough to be annoying. Any ideas?
