No Display

[ddog373]

Friend just upgraded pc, Ryzen 3800x, Gigabyte B450 Aorus Pro, gtx 1080ti, 3600mhz DDR4 16x2 Corsair Vengeance. Long story short his monitor cant get a display or get into bios but everything seems to be working in the tower itself as in fans and power. Already tried 1 ram stick to make sure they weren't dead it still turned on. Any suggestions?

is it possible that at this very moment, the display cable decided to die? has happened to me before.

What is the PSU did they try using another monitor or is the hdmi cable broken?

The cord works he is using it to stream from his laptop to the monitor so cord is out of question

Looking into it, there's about 15 different BIOS updates for the B450 Aorus Pro and from revision F1 to F32 there's no support for the 3000 series Ryzen chips. F40 and up is when the support for the newer 3000 chips came into play. It's a long shot, but if that board your friend got happens to be from (really) old stock, it's likely it would have an older BIOS. 

 

Sometimes they show the BIOS revision on the motherboard box SKU/ID portion, take a look and see if it's there. I'm not saying this is your issue 100%, but considering the symptoms you've described, this would be my first stop.

 

FYI: BIOS F40 came out 05/16/2019. So if the board has a packaged or manufactured date on the box and it's from before then...

 

*EDIT: I have taken a look into whether or not the B450 Aorus Pro supports Gigabyte's Q-Flash, which allows you to flash the BIOS without a compatible CPU installed. So far haven't found much, but they don't list the Q-Flash utility in the downloads section for the motherboard, so I'm kinda thinking it's a 'no'.

 

*double edit: No. It does not support Q-Flash plus which is on the B550 boards and allows a flash with no CPU. So hopefully it's something else, or you're gonna need access to a 2000 series CPU or APU.

Had this issue a while back where my PC would not post however, the fans and LEDs would still turn on. 

 

My Mobo was displaying Q-LED lights still which the light was stuck on the VGA light indicating there was something wrong with the connection between the GPU and the board. It later turned out to be a dead GPU. Could be a good start to try there since it seems your motherboard is receiving power but if this leads to nothing I would probably be leaning to more of a dead PSU situation. I'll leave a link to what the Q-LED lights look like on your board below if you are not familiar.
