Need help with Black Screen

[Goldilock]

Spec:

Ryzen 5 3500x

16GB RAM

FSP HV 500 watt PSU

Gugabtye B450M Gaming

RX 5700 XT

 

2 weeks ago my PC had video glitch, then video went blank. I cannot get any display ever since, not even to the Bios. The fan and everything would spin but the monitor would not display anything.

 

I had same case last month. But last month power cycling temporarily fixed the issue, now not anymore.

 

Things I've tried so far:

1. Clearing CMOS

2. Use spare CPU A8 9600, for onboard display out but still no display signal

3. Use different RAM

4. Power cycle

 

I'm starting to lose hope since it cannot even display BIOS. If anyone  had same issue, any feedback will be appreciated

I would try a different monitor, unplug all of your monitors and try a known working one.

 

Buy a cheap mobo that works with your cpu and see if you can even get anything to post (like <$100) if it does, then I'd blame the mobo

 

It seems strange that both the integrated graphics and the gpu refuse to display anything, I'd say it'd gotta be the motherboard, but without additional testing I can't say for certain.

I plug the monitor to my work laptop, it works just fine.

 

Thanks, I still can't rule out mobo issue.

 

Does A8 9600 works with B450M?

 

I remember having same issue waaay back installing ivy bridge CPU on sandy bridge mobo without BIOS update. It display blank too.

These are the motherboards that PCPartPicker states are compatible with an A8 9600, but PCPartPicker also said that my X370 Pro wouldn't support 128 GB of RAM and it clearly is, so take this with a grain of salt
