OK let me start off with specs: 

Asus prime z390-a

i9 9900k

2080ti ultra 

1tb 970 Evo plus m.2 SSD

32gb 3000mhz corsair vengeance RGB pro- searched on the website apparently the mobo doesn't support 4 dims of this ram but keep reading. 

 

Problem :

Pc turns on all LEDs flash blank monitor screen

Dram yellow light on the motherboard

 

Attempted solutions: 

removed CPU checked for bent pins with a magnifying glass - No bent pins and did not fix the issue  

Removed 2 ram sticks - placed ram in b2 and a2- Still blank monitor screen 

removed GPU - still blank screen 

Booted with HDMI and display port- still blank screen 

 

Need Answers:

FYI Not my first pc build 

Is the mobo dead?

Try each stick in individual slots and see if you have a bad stick and/or bad slot on the board.

Well good tip I tried that out so all my ram cards are good but I can only run 1 at a time won’t let me boot with all 4 or just 2 is that just a bios setting?
