    0xD1 DRIVER_IRQL_NOT_LESS_OR_EQUAL is an error that is usally caused by faulty drivers.

    From what you have provided and after considerable research the driver simdrv.sys belongs to the SHUNRA\Cloud WAN Emulator Miniport by Shunra Software.

    The Shunra/Cloud alters your IP traffic flow within its host. If you search for this software you can read up on it. Try updating the drivers from Toshiba.

    hi. I had some issues getting the right driver. I preferred uninstalling the Shunra software and waitied to see for any issues as i wasnt aware of a particular reason for this software. Its been 2 days and no issues so looks like am good for now.

    Thanks.
    PS: is there any risk involved without the software.

    Honestly I don't know working knowledge concerning emulaters but reading this ino from said company http://www.shunra.com/wan-emulation.php that unless you are in networking I would say not.

    It sounds like this software came pre-installed on your laptop. Correct?

    frequently we can UNINSTALL a driver and reboot to allow windows to Autodiscover an appropriate driver.

    Do this one device at a time, eg
    video, audio, ethernet, USB​
