First post here!
I have an Asus Prime B450M-A motherboard purchased with a preinstalled Ryzen 5 3600 CPU and stock cooler. It has worked fine for about two years, then one day it would no longer start when I pushed the power button.
I suspected the PSU, so replaced that. There was no improvement.
I then replaced the motherboard - again, it still won't boot.
After switching the PSU power switch to on, a light in the case lights up. When I press the case power button, it lights briefly, goes out again and nothing else happens. The power button no longer lights when pressed unless I turn the PSU power off and back on again and then I press the case power button.
So I am wondering if the problem might be the case power button. Or, much worse, the CPU.
What should I be doing now to eliminate more potential faults?
Many thanks.
