Solution 1 – Update your drivers and Windows 10

update drivers

Drivers are an integral part of every operating system since they allow your PC to utilize your hardware.

In case a certain driver isn’t working properly or it has compatibility issues with Windows 10, you’ll have to update it in order to avoid getting BSoD errors.

To update a driver, you just need to visit your hardware manufacturer’s website and download the latest drivers for your device.

It’s important to update as many drivers as you can, so be sure to download drivers for your motherboard, chipset, and every other major component.

Alternatively, you can also use Device Manager to download all the necessary drivers, but it’s usually better to download the drivers manually directly from the manufacturer.

Downloading drivers is important, but it’s more important to keep Windows 10 up-to-date with the latest updates.

Many updates bring new features and security improvements, but most importantly, these updates fix many bugs and compatibility issues with certain hardware and software.

Since hardware and software compatibility is the common cause for BSoD errors such as IO1_INITIALIZATION_FAILED, you can see why it’s important that you update Windows 10 on a regular basis.

Update drivers automatically

Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically.

Using an automatic driver updater will certainly save you from the hassle of searching for drivers manually, and it will always keep your system up-to-date with the latest drivers.

Tweakbit’s Driver Updater (approved by Microsoft and Norton Antivirus) will help you update drivers automatically and prevent PC damage caused by installing the wrong driver versions.
