Ask MS-AA71 / MSI WindTop AP2011 - Random Shutdown

[matheus30]

I have an AIO MSI WindTop AP2011 with the MS-AA71 board that after 10 min/2 hours or 1 day turns itself off. CPU temperatures ok, tried another AC, in Memtest it also turns off.
Today I have to test all the voltage surges on the oscilloscope, but the curious thing is that the CHOKE10 is between 58-62º a second after connecting the AC.
Does anyone with this board have the same problem or remember those temperatures in the coil/choke? Being the 19V to 12V and 8A it can be normal.
Other ideas?

Thanks!
