• Just a thought. I've worked places where the system support staff would handle system updates, updates of common applications, and suchlike outside of normal working hours. Does your company do this? Could they have done this last night (even if they normally don't do it)?

    Do you have anything that processes updates/upgrades automatically (Windows Update leaps to mind) that could have run last night?

    Was your machine on or off when you left last night? when you came in Monday morning?

    Could there have been any environmental weirdness, e.g. a power outage?

    I would expect that some of these answers are "no", simply because you say that there wasn't anything peculiar in the event log; however, I'm never sure which of these sorts of things get logged and which don't.

    I have no answers for you - however, answering these questions may give someone the insight needed to help you out, or to make your own educated guess.

    Good luck.
