My computer is connected to a apc surge protector, while it was in stand by mode I turned off the switch of the extension cable thinking nothing of it. The next morning it stopped booting properly. No signal, Caps lock etc not blinking on my keyboard. My Loud hdd not making usual loud under load noises. Nothing. My msi motherboard signals a error with the CPU. What could it be?
My system:
Ryzen 5 1600
Gtx 1070
MSI b450m pro m2 max
Ram 2x4 gb crucial ballistix sport

I should have mentioned that I cant Even get to bios, my Monitor is just black as if it was off. The Fans of the CPU and gpu spin. I have a corsair vs 650
