PC was kept on (idle), when there was a power outage and it turned off as usual. However after power came back, the power indicator of GPU wasn’t on, but my backlit keyboard was glowing just as it should.

Trying to turn the PC on as usual, it didn’t turned on and there wasn’t any sign of life, no fans, no lights whatsoever. I unplugged the PSU power cable (from wall outlet) and plugged back in after around 5 seconds and it worked fine.

But 2 of my USB 2.0 ports in the back of the mobo doesn’t work now.

What’s causing problems, PSU or Mobo?
