Mobo fried by brownouts?

I was getting about two or three brownouts last week but everything was working fine. This week I was playing a game and listening to music, when I suddenly decided to try and move the monitor DP wire from in front of the case to the back as my mouse and keyboard kept getting tangled around it. Knocked down my router on top of PC case which made the case shudder a bit. This caused the system to hang, my game froze, and headphones had static noise coming from them. I held down power button but PC wasn't shutting down. So I flipped the switch on my PSU on and off. The next time I tried to turn it on the Mobo did not light up, usually I get an orange light. I look inside the case and see RAM LEDs are on, CPu fans spinning, case fans spinning, monitor no display.

I went through basic troubleshooting like taking out CMOS battery, reseating ram, power cycle the PSU. Turned it off for a day or two and did the same thing later - still the same. Im convinced the Mobo is fried. No second system to test Gpu on though could be it as well but I doubt it.
