AMD Error Code 43: 7 Proven Fixes

AMD Error Code 43 occurs when Windows stops a hardware device because it encounters a problem. This error is commonly associated with AMD graphics cards and can result from outdated drivers, hardware issues, or software conflicts.

I’ll show you how to fix it, so let’s get started.

Quick Fixes

Try these simple steps first:

• Update Windows: Press Windows + I > Windows Update > Check for updates > Download and install.
• Power cycle the computer: Turn off your PC, unplug it from the power source, wait a minute, then plug it back in and turn it on.

Update the Driver

Outdated or corrupted drivers are a frequent cause of AMD Error Code 43. Updating the AMD driver ensures compatibility with your system. Here’s how to do it:

1. Press Windows + X and select Device Manager.

2. Expand the Display Adapters category. Right-click your AMD graphics card and select Update driver.

3. Choose Search automatically for drivers. If Windows finds a new one, follow the on-screen instructions to install it.
