Downloading drivers manually is a process that carries the risk of getting the wrong driver installed, which may lead to severe malfunctions.

Big-time gaming can be done without crashes, lags or freezes by keeping all drivers up to date and error-free. Manual checks are hard to perform, that’s why we recommend using an automate assistant that will scan for fresh driver versions daily. Here is how to use it:

  1. Download and install DriverFix.
  2. Launch the software.
  3. Wait for the newly installed app to detect all your PC’s faulty drivers.
  4. You will be presented with a list of all the drivers that have issues, and you can choose the ones that you want to fix.
  5. Wait for the driver download and fixing process to complete.
