Many blue screen errors are blamed on outdated, corrupted or missing device drivers. BAD_SYSTEM_CONFIG_INFO is no exception. Updating drivers should always be your go-to option when something goes wrong with your computer or system. Whether you choose to update the device drivers manually, using Windows Update, or you use a trusted third party product, it’s essential that you have the latest correct device drivers for your operating system at all times.

If you’re not comfortable playing with device drivers, we recommend using Driver Easy. It’s a tool that detects, downloads and (if you go Pro) installs any driver updates your computer needs. Here is how to do it:

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. You need the Pro version of Driver Easy to do this, so you’ll be prompted to upgrade.
