Hi all I recently brought a x399 motherboard , I?™m struggling to test to see if it?™s fully working, before I spend out in a decent graphics card ??
I currently can?™t get a display , I?™ve got a range of old graphics card I?™ve been trying I can?™t get over no onboard gpu , So 350w power supply 1x 4gb ddr4 1x Kingston ssd 240gb Threadripper 1920x Pc specialist 120mm cooler Nvidia gt620 - test gpu
I get no output from vga or display port ?
Green light when I power in its turns to blue Blue light next to gpu card All fans are running looks fine
Any ideas ?

Board model?
With threadripper you really need to pay attention to the CPU installation. The CPU is so large that it's very easy to have it sit unevenly in the socket and not initialize. Follow a good tutorial on installing it off Youtube to be sure it's properly seated.
Make sure your RAM is installed in Slot A2 (second slot from the CPU on the 24pin power side) The Gt620 should work with x399 boards That PSU is underpowered for Threadripper, you want at the very least a decent 400w (80+ certified) PSU. If it's not providing enough power the CPU will not initialize. Once everything is installed correctly, clear CMOS then power on the system and leave it powered on for 10 mins or so. The first post on x399 systems can take quite some time before it gives a display. My 2950x system took about 3 mins to POST the first time I powered it on. After the initial POST however it comes on normally. This is due to memory training and is normal for the platform.

The RGB tells you nothing, what you want to look at is the debug display next to the power and reset buttons on the board. It should display POST codes, Power on Self Tests. Each test has a code designation and any code that freezes will remain on the display to tell you where the POST process failed. If you are getting nothing on the debug display then you likely haven't connected the 8pin CPU power to the board or you have the wrong one connected. Take a look at your user manual, you can find it on ASRock's website if you don't have a hard copy, and make sure you have everything connected correctly.
If you are getting codes and one of them is remaining on the display, post that code here so we can figure out what it's indicating as the problem.
