Secondly, check and ensure all cables within the computer are connected correctly.

If you ensure that all cables are connected without problems, and the Event ID 41 error persists, try other methods.

Method 2: Remove all external drives

External drives can draw power from your computer, then cause the Kernel-Power Critical 41 error. If you’re using some external drives such as external USB devices (aside from keyboard and mouse), remove them and see if the error occurs.

If the error is gone, the cause is the external drives.

Method 3: Update the graphics card drivers

Then you can double-click on the downloaded driver file, and follow the on-screen instructions to install the driver on your computer.

If you find it hard to update the drivers manually, you can do it automatically with Driver Booster.

With Driver Booster, you can update the graphics card drivers with just a few clicks.

If not, you’ll need to replace it on your own. Before you buy a new PSU, it’s recommended you test it. If you have no idea how to replace the PSU, you should go to the computer repair store to have it fixed.
