Well, managed to test my cpu, ram and videocard with another board, all work ok, unfortunately the owner had an 3700x so I could not test my Asrock mobo itself. Still all is pointing to the mobo being somehow bricked. Strange that the fans are spinning on both cpu and vga, still no beeps from the speaker. :-(

Did it ever beep before? and when it did, what were the issues?

I seriously think that it's some serious hardware issue because you didn't make any change. Was there anything like voltage fluctuations? Did something like this ever happen before? Were there any issues like this with that PC?

Anyway, try these basic things:

1. Reset your BIOS (Use the 2-pin jumper cap and short it with a metal object for a minute or remove that button cell battery for 5 minutes and put it back in)

2. Remove the GPU and plug the display into the motherboard video output.

Tell if it displays anything. Try entering the BIOS by pressing F2/Delete or whatever key specified when it starts.

You did have the computer off when you cleared them right? And did you do as beenthere suggested and pull the battery for a few seconds. Make sure you unplug the computer and push the power button first to clear any residual energy, then remove the battery for a few seconds and replace. Does the computer act like it's running, when you turn it on? You know, keyboard lights flickering, mouse lighting up, maybe a hdd indicator flickering. To turn it off do you have to hold the power button down for apprx 5/6 secs before it turns off or does it turn off as soon as you hit the power button for 1 sec? If it's the 1 sec deal then you're either in bios or they won't even load. Hope they didn't get corrupted the first time you reset them. If it's the 5 second deal then the computer is most likely running, you just don't see anything. If that's the case try re-seating the video card or try a temp video card. And make sure you plugged everything back up after taking it apart the first time. Might have missed a power plug of something simple hopefully.

Hi, thank you for reply, tried option 1 , even left the motherboard with the battery unplugged overnight. Cannot use the motherboard video output as I have a Ryzen 1600, no onboard graphics in it :-). The whole point is that it does not display anything, no bios menu at startup or whatever, monitor just shows that it receives no signal. As I tested, the vga card, memory and cpu work fine on another motherboard. I am currently seeking a cheap ryzen apu to make a final test before declaring the mobo dead.
