    BSOD 0x0000001e or 0x000000c4 or 0x0000007f all caused by igdkmd64.sys



      My IT admin recently upgraded my old Lenovo ThinkPad X220 with an SSD, a clean Windows 7 Pro 6.1 7601 SP1 install and 2x4=8GB RAM. As expected, my machine is now much quicker but I started having Blue Screens Of Death every now and then. I don't think the BSOD are related to specific actions, they seem rather random. In less than a month I got 8 BSOD incidents, five of which were 0x0000007f UNEXPECTED_KERNEL_MODE_TRAP, two were 0x0000001e KMODE_EXCEPTION_NOT_HANDLED and one was 0x000000c4 DRIVER_VERIFIER_DETECTED_VIOLATION. All of them mentioned that were caused by driver igdkmd64.sys.

      I have already tried the Intel Processor Diagnostic Tool and I got a 'pass' in all tests. I have also checked the device manager and all drivers seem to be up to date. My IT admin tried removing each of the two 4GB RAM in turn but I got BSOD with all combinations.

      I attach the five most recent dump files for your reference.

      Any help will be appreciated. Please provide step by step details because I am not an IT expert.

          Hi Wisdom21


          First I would recommend updating the System BIOS on the X220 with the latest from the Lenovo website. Also, be sure all the drivers are updated as well with the Lenovo validated drivers and be sure all Windows Updates are installed.


          Your system has an Intel HD Graphics driver that has been customized by Lenovo specifically for your system. They usually add customization for docking behavior, power saving, display color and brightness settings, etc.

          You can however overwrite the customized drivers with the generic Intel HD Graphics drivers but you will lose any Lenovo customizations to the driver. If you do want to install the generic driver, follow the following instructions exactly. If you are not happy with the updated driver you can always roll back to the Lenovo customized driver or re-install the Lenovo driver.


          Download the zip version of the Intel HD Graphics driver here:

          64 bit http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=24696


          Unzip the file to a folder on your desktop and follow these steps.



          1. Login with administrator privileges

          2. Open Control Panel

          3. Open Device Manager

          7. Click on "Update Driver" button

          8. Click on "Browse my computer for driver software"

          9. Click on "Let me pick from a list of device drivers on my computer"

          10. Click on "Have Disk" button

          11. Click "Browse"

          12. Navigate to the folder that you unzipped the Intel HD Graphics driver to

          13. Navigate to the Graphics sub-folder

          14. Double click the igdlh64.inf or igdlh.inf file <-- depends on if you have 32 or 64 bit OS

          15. Click "OK"

          16. Click "Next", Driver should now be installing.

          17. If successful, click "Close", Reboot.
