  • I received an error code 31 on Lenovo X230 network (wired and wireless) adapters. I removed the “old” drivers, by deleting all driver files, downloaded the latest drivers from the supplier (both from Lenovo and Intel), and after installed a “new” driver i got a same error message. If I boot from a different media – portable Win7 on USB drive – the network card is working fine. Reinstalling the driver is not solves the error. What can I do?

  • Hello. I recieved the same error code 31 at my Nikon D5100 camera. It worked perfecttly until my father reinstalled Windows 7 for not working properly…. At first I searched for Nikon drivers to install. Than I saw that not even a stick works so I thought that the problem is not with my camera. I’d tried to install the updates for the device. It’s telling me there are the best drivers for the device. I updated Windows. I’ve even tried to put the card from the camera in the notebook (Asus K50IJ series ) but still it’s asking me to update drivers. It appears “Mass storage device” with an “!” . I tried to restore the system and for the date I choosed it appeared to be unable to restore. It failed. … Nothing seem to work. It is possible that something is not installed along Windows 7? Did he forgot to install something? How can I fix that? Did I have to reinstall Windows again?

    Please help because I’ve just spended 7 hours trying to make this work… I can’t transfer the photos from my camera :( Write me on my email sheesha666@yahoo.com or here…But help me somehow… Thank you so much! Happy Easter!

    • Are you seeing the error code 31 in the Device Manager? If so, it is a Driver error indeed but if not it may be a system error which would need to be addressed differently. Did you run a free Drivers Scan at http://www.drivers.com/update_digital_camera_drivers_main.php – when the missing Drivers are identified you can choose to search for the Drivers yourself or register the software to enable automatic Driver updates.
