Screen Freezes / PC Hangs up


  • I installed the developer preview yesterday. It worked fine, had one or two explorer.exe crashes but nothing much for an Alpha Build.

    This morning at work I connected a secondary screen and after a while the screen randomly freezes up and the PC hangs up for a good half a minute on average. I removed the secondary screen and the problem is still persistent. I dont mind random crashes here and there but the freeze up totally hinders any work / play on windows 8.

    I am running a dell i5 m480 2.66 ghz / 4gb ram / x64 / AMD Radeon 6500M series.

    I am re installing windows 8 and will forgo the auto downloaded video driver and install the official one from the AMD Radeon. Will keep you guys updated on this issue / if it is resolved.

    Please discuss here if you are facing a similar issue.

  • I noticed that sometimes it starts freezing whenever I mouse over to the left side of the screen (to bring up the "get back to previous app" UI). Whenever I do that, it freezes the screen for 30 sec - 1 min. If I have audio/video playing, the audio continues, but the video freezes (the audio from the video continues playing) and when it unfreezes, the video fast forwards until it catches up.

    As long as I never move the mouse to the left edge of the screen, everything works great. It also doesn't freeze when I mouse over the left bottom of the screen to bring up the charms menu. It also doesn't freeze if I don't have any previous programs. It seems to be a problem with bringing up that specific UI.

    If I wait for it to unfreeze without moving the mouse, I can drag in the previous app correctly.

    I installed the latest Windows 7 drivers from AMD for my video card and not the experimental drivers from Windows Update, so this doesn't seem to be the factor.

    It also doesn't happen every time, but seems to select to either freeze or not to freeze on boot. If it freezes, it will freeze every time. If it doesn't freeze, it will never freeze until next reboot.

    My PC is custom built Core i7 2.93ghz / 8gb RAM / Asus P7P55D-E Pro MB/ Radeon HD 6870 graphics running 64-bit preview

  • video memory degradation..

    The Desktop Window Manager is experiencing heavy resource contention. 

         Scenario : The Desktop Window Manager responsiveness has degraded.


    The Desktop Window Manager is experiencing heavy resource contention. 

         Scenario : Video memory resources are over-utilized and there is thrashing happening as a result. Reducing number of running programs and open windows may help resolve this condition.

  • There were few Windows Updates happened recently. See if you can remove those. Try to reinstall your display drivers. Nothing works try to do a System restore to earlier settings and see if freezes.

  • do not look anything like "metro"

    what you need to close are the Apps came with windows (like tweet@rama, picstreem.. etc)
