Windows 7 - Boots fine in standard mode, will not boot in safe mode

    Question

  • Installed Windows7, everything working great.

     

    Because Windows 7 won't let me force a resolution on an LCD screen and insists on it being 1024X768 I want to run Windows 7 in safe mode, which WILL let me bump the resolution.

     

    SO, I boot to safe mode and it hangs at classpnp.sys.  Tried recovery console, renamed classpnp.sys, still fails at that.

     

    How can I either get past the classpnp.sys or force Windows 7 in regular mode to let me set higher resolution?

     

    Thanks!

  • Hi,

     

    Thanks for posting in Microsoft TechNet forums.

     

    Do you have any external USB hard disk connected to the computer? If so, please unplug the external USB hard disk and see if you can boot in Safe Mode.

     

    There are a couple of similar issues in forums that you can visit for references:

     

    “classpnp.sys” “Windows 7”
