    Win 8 Self starting and shuting down


    I've been testing this Win Consumer preview for a little over a month now. For the most part it has performed just fine. No freezes and fast response for an olf spare computer. But I've noticed some odd behavior that I'd thought I'd ask around about.

    Win 8 Seems to have a new method of doing updates. My Cannon MP560 wireless printer driver initially would not work, but when I did a re-install of win 8 the cannon drivers that were on the initial Win8 pack uninstalled them selves and allowed the ones from the cannon CD to install. This fixed the problem. Initially the system would not allow me to install the older drivers from the CD. Lately I've noticed that when I shut down my test system. The monitor shuts down(does not display anything), but the CPU stays on. Sometimes as long as five min. On several occasions the system has turned back on during this unexplained CPU activity. The monitor has come back to life and it's wait for me to sign in.
    To me it looks and feels like Win8 is doing updates during this period, but why would the signal to the monitor be turned off? It feels like they are trying to hide what it's going. Today however, I left the system on for several hours and when I came back it was off. No notice that it crashed or anything. It was just off. I've never had a computer do that; if it was the Hw there'd be a notice and a logged even at least mentioning and unexpected shutdown; if it was software related there should be a long list of events in the logs.

    Hi,

    Uninstall any 3rd party antivirus or firewall in safe mode using the special tool for the product(s) in safe mode.

    If you still require help, run the tool found in the top thread of this subforum here and paste the zip it tells you to make to a new post here. We'll see what we can do.

    Other that that, you might not even have an issue. Google what sleep and hibernate are. In addition, Windows has the ability to turn off monitors to save power. You can check your power options settings. I'm on Ubuntu at the moment, but from memory - right click desktop, personailze, screen saver, change power options - leads you to the options.

    On second look I did find the crash entries in the logs, but I still don't understand why the system hides the update process. Turning off the monitor and leaving the CPU running, when I've requested a shutdown, gets my paranoia running too. And if I shutdown and walk away it might come back on that is really unnecessary.

    There is no update process being hidden by the system.

    If you want to fix those crashes from happening, you're welcome to post the logs as per my previous post.

    For rectifying the auto ON issue go to Control panel>>Device Manager>>Network Adaptors. Right click on ur network adaptor and click "properties". Go to power Management tab and uncheck " Allow This Device To Wake the Computer". Do the same in BIOS power management too. I hope it helps.
