Question ASUS Prime B350-PLUS turns on, but no display

[dhal277]

As mentioned above, I didnot used this board since I upgraded to B550, before it was working perfectly fine. LEDS are on, but when I press the start button, Leds are turning off, fans are spinning but nothing happens at all. Last bios revision was 5204.

thats what I tried so far

3 different cpu - 2200G, 1200, 3600
2 different Ram stick - 1x4 Crucial 2400Mhz, 1x4 Kingston hyperx 2666 mhz
2 different PSU-s, (corsair vs350, cooler maste bronze 650W)
1 dedicated gpu - RX 460
Tried all ram slots, all video output hdmi, vga, dvi with hdmi adapter
Took out the battery to reset CMOS

nothing really helped. Any idea?

Did you manually reset the BIOS at any point during these changes?

Not really because there was no display.

Or how do you mean manually?

To manually reset:

Power system down
Remove all power connections (power cable, display, powered speakers, etc.
Remove the motherboard battery
Press the power button to discharge any residual power in your components (yep, I'm serious)
Wait a minute or two
Reverse the steps..battery..connections.
Power on.

The motherboard manual will also tell you a way to do with a jumper.

Yep that was also done when I take out the cmos battery

At this point, sounds like a dead motherboard. Possibly damaged by a short or static discharge at some point.

What really bothers me, that the Leds are on, even the PCI slot has some LED lights but there are no debug Leds... So you think the board is dead?

Just means it is getting power from the PSU.

Is this motherboard in a case, or outside of one?

Outside, there is an antistatic Bag below it and my foam pad.

Understood. I was assuming that given all the swapping you have tried. I was concerned about shorts/grounding by stand-offs/mounting points.

She sounds dead at this point.

Do you have a speaker attached to the speaker header? Any beeps?
