To identify the driver causing the error, you need to inspect information provided by the BSoD screen. The name of the driver should be written after the error name and should look like this: “What failed: [driver name]“. It may also be written in brackets.

In case the system can’t find the updates automatically, you can visit the official website of your motherboard manufacturer and try to check for new driver updates there. You can also use online search engines to find driver update if it belongs to an add-in card or other hardware, but make sure you visit trustworthy and official resources only. Do not trust various third-party websites or you might download something damaging or malicious.

If you find an updated driver release on a trustworthy source, you can download it. Use the instructions provided above, but in step 3, choose Browse my computer for driver software instead.
