Hi.
I have an old FX AM3+ system that has stopped booting. When it's plugged in and the power button is pressed nothing happens. The power supply does not start the fans don't turn on in the case or on the GPU.
Is it perhaps the power supply that has failed? Or could it be something else? Perhaps the motherboard. Is there a way to check if the power supply is OK outside of the case?

Any ideas on how to approach this issue would be very welcome.

Regards Steve
