Solved Switched of electricity, now PC won't start.

Had to turn of the electricity to disconnect some plug sockets for painting. Turned electricity back on but now the pc shows this:



The pc hasn't touched in all of this. It was shut down correctly, it wasn't moved. Any help would be appreciated.

Nm. Bios was in need of adjusting. All well now.

I think your Bios battery is dead and that you lost Bios settings when the power went out.
I think that's why that AMI screen was shown.

Your service manual should be available for download from your motherboard maker's support site.
The service manual will explain how to replace that battery. It might just be a simple coin-cell battery since you have a desktop computer.


Best of luck,

Change the BIOS battery. I once had a problem where a power glitch affected the BIOS and had to reflash the BIOS.
