I builded my first pc yesterday specs ryzen 5 5700x with a b550 a-pro mother board and I tried running it but from all the sudden I find out a white light flashed in the mother board and next to it , it’s written Cpu , and another thing is that I couldn’t shutdown the pc using the power button from the case , . so I had use the one that attached to the psi ,and today when I got the gpu , and plugged it in , there was no output and the fans on the gpu doesnt works I tried flashing bios using a usb drive , and yet not result , I removed the cmos too for 5 minutes and plug it back no result the same cpu light keep lighting , so I removed the cpu and plug it back still no result ? I will really appreciate any help possible
