Unfortunately, it hasn't changed. Possible motherboard error because there is an error message when switching on. but when Windows loads, there is no error in the device manager

Does the image still appear after a minute?

[O.Szilard]

Yes after 1 minute, then an error message, enter and Windows loads. after that the machine works flawlessly.

We will prepare it as it came out of the factory

Try and report back.

As SMDFlea mentioned, use your original BIOS. Use your original 16Mb dump and the attached 32Mb cleanME.
