Power outage while both my PC was on. Both system has Eva supernova 1300w pus. House power was restored and one of the system failed to restart. When I try to restart I see the system cycling thru some code show on the motherboard led. The last code is seen is 4F then it's just keep rebooting with no code. I thought perhaps the pus was fried. So I got a spare brand new 750w psu. Installed and got the same thing. Maybe the motherboard fried? I have a brand new motherboard that I bought it years ago have it repaired as spare part while I bought a 2nd one.. It's a X399 AMD 16 cores threadripper. I am thinking install the motherboard. I have remove the cmos battery but the same. What do you guys think the cause?
