Hi, I'm sorry if I'm in the wrong area, but I'm genuinely stumped with a new build.  I am using the Asus Z790A Gaming Wifi II motherboard with a new Core7 14700KF CPU.  Kingston Renegade Fury ram 2x16GB (in the correct slots).  With my luck I had a faulty PSU, (ASUS RoG STRIX 850W) that I replaced, so that problem is solved.  I originally started the system with my old video card, an Asus GTX 1060 6GB, and I get no video at all.  Thought maybe it was the old card, which works fine in my old system, but now that I have my new card, an Asus Dual RTX 3060 OC 12GB, it is still doing the same thing.  Flashed the BIOS using the button on the back since I do not have onboard video (doh), and still no go.  Reset the CMOS using the button on the back, removed the CMOS battery for 15 minutes, and still no luck.  Reseated memory.  Tried 1 stick.  Tried the other stick.  No bueno.  On startup, the red CPU light comes on and promptly goes off, followed by the DRAM light that goes off, then the VGA light comes on and goes off, then the green boot light stays on, obviously due to no OS.  Really stumped here.  I'm using a Hyte Y60 case, so maybe the riser cable?  

Should also mention, no beeps or anything during startup.  All the fans run, and power to the LC II 360 AIO liquid cooler, pump, etc.

Oh, I also carefully removed the CPU to have a look, and nothing looks cooked or damaged on the CPU or the motherboard.  I also assume the CPU light would be on if that was the case.

 

I guess my big question is, when is it time to throw in the towel and just R&R the mobo?

 

Thanks in advance.

If you suspect it to be the riser cable possible, have you tried booting with the GPU plugged directly into the motherboard? That would be a logical step in my eyes.

Sadly, the Hyte Y60 doesn't allow you to mount the card in the normal position.  In order to even test this, I'd have to pull the entire system apart and run it outside of the case.  Unless I hear of some other possible solutions, I will give that a shot.

Take out riser cable, plug GPU in, hold it in place and level it using your hand or something sturdy enough, like lego or something.

Try turning it on.

 

Hopefully they atleast make it possible to slot in GPU horizontally for just a moment.

 

 

Sounds risky and troublesome, or the case doesn't even allow such thing at all? take out motherboard off pc case and do troubleshooting ontop of motherboard box.

I actually did that as well.  I unscrewed the riser cable from where it was mounted to the case and plugged it directly into the graphics card in case it just wasn't seating properly.  Still a no go.  

 

I will carefully remove the motherboard from the case tomorrow and plug it in directly.

So, I "breadboarded" the system and plugged the video card directly into the motherboard, and no video still, regardless of the riser cable.  Putting in a return on the motherboard since no error lights are coming on but the boot light.
