Question After power surge PC won't boot, still won't boot after replacing MOBO and PSU

Jul 7, 2020
Hi all,

I'm at a loss here, hope someone on here can help.

A few weeks ago my circuit breaker tripping caused my PC to not power on anymore.

What would happen is that both my MOBO would flash LEDs and the fans would run both for a split second.

After looking online I replaced both the Motherboard and the PSU but exactly the same issue remains.

I have removed the GPU and switched the RAM and the it still does the same thing.

Any idea here? I assume my CPU must be fried by process of elimination, but I am also wary of the cables with my case and if they're causing the problem.

Any insights before I blow any further money would be appreciated. Thanks in advance.
