Hey folks just built my new PC on a B550 Elite and 5800X and no display on screen when powered on?

The board was RMA'd as I couldn't update the bios the company has seen done this and sent the board back to me.

Things I've tried
Reseated Ram and tried using 1 stick of each
Reseated Graphics card
Cleared CMOS

Things I'm yet to try
Different Display cable although worked fine last night
Different GPU although again Worked fine last night.
 
Has this been built in the case? I would suggest testing the CPU, mobo and RAM outside of the case to make sure everything works then build in the case. Test it on the mobo box is fine, this will rule out any short in the system.
 
My previous system was in this case and it worked fine that would mean I would need to rip out my PSU which is currently all cable tied.

Also everything powers on if it was short circuiting it wouldn't power on.
 
No bent pins or LEDs on the motherboard Ive tried the second pci-e slot with a backup GPU and I got 3 flashing white lines on the screen briefly but can't seem to get it to do it again.

If you got a diffrent gpu to try or test yours in another system. Same with the monitor and cable.

Just gotta try to rule things in or out.
 
I'm getting another cable to try later and this is another GPU I'm trying was stuck on a black screen a minute ago so that's something and when I switch inputs it says Displayport is connected
 
Where have you plugged the display cable to? Motherboard IO or the graphics card IO?

what does the board debug LED say. Any activity on the PSU when booted up?
 
pull everything out of the board leave CPU in socket and cooler in it. pull power from PSU and pull battery out of board and shortcircuit CMOS jumper for 30s.

then pull everything together. if no joy, test wiht another PSU.

you definitely sure you got all the cables etc seated properly.
 
Yep I've built many a PC's and had no signal problems before but they have always been to the RAM but I've tested in every slot so don't think that's the problem
