Good evening,
I just received an Aorus b450i pro wifi from a friend, who had it running for the past year in his own pc (so i know it's working).

No matter what, i couldn't get any video output through either the onboard or GPU outputs.

The motherboard apparently POSTs because there's the single short beep that says "system ok".

Here's what i tried so far
  • Changed my CPU from a 2600 to a brand new Athlon 220GE
  • Reseating all cables
  • Reseating the RAM
  • Moving my single stick of ram to the other slot
  • Tried on both HDMI and DP on the GPU
  • Put the Athlon, removed GPU, tried both HDMI and DP on the onboard video
  • Put the motherboard on a piece of cardboard to make sure there is no short-circuit
  • Swapped PSU to my main PC's PSU
Tomorrow i'll try resetting the CMOS. That's a very weird case to me though...

Any idea?

Not all monitors switch to the input that has the signal from the pc automatically so make sure it is set to the one you've connected the pc to it with.
Hiya,
Methodically went through all the selectable inputs on my monitor while trying the different outputs and cables, still nothing.
