I just bought a new PC and got most of the components today and put it together. This is not my first pc as I've put together about 20 but first one in about 7 years.
The motherboard is ASUS Prime Z790-A. The CPU is Intel 13900K. Memory is 128GB Vengence. GFX is Intel A770.
Initially it did not post but I think I might not have seated the memory(I put in one stick first) or put it in the wrong slot(didn't realize that one might have to use specific slots).
Anyways, after a few tries nothing. After a little messing around to see if I missed something(moved the memory around an nothing) and realized that the white light was VGA issues(the labeling on the MB does not align with the LED's so I thought it was some led off to the side) I tried a few hdmi cables and nothing. I don't know exactly what I did but basically I removed the A770 from the system and was trying the built in hdmi port trying to use the CPU's GPU. It would not post. CPU led was fine, DMM was fine... but white light. I tried all the standard stuff and looked online and that but nothing.
I couldn't get it to post for any reason and it was always the white Q_LED. Well, I figured something was bad, cpu or motherboard.
But I went ahead and put the A770 back in since all I could do was retry it and hope that it wasn't the MB and it actually posted and I could get to the BIOS. My HD's are not in yet so not really much to do.
I noticed that in the bios there would be, here and there, a few flickers in the screen(seems to go white for about 100ms) but it didn't happen much and seemed to just happen at the start.
Since I had nothing else to do I decided I should run a mem test to verify my memory so I put in the 3 other sticks(I did mess around in the bios a little just seeing what was different than my previous ASUS but didn't do much). The screen in memtest flickers constantly, about once every 10 seconds.
So given these issues I'm wondering if I have something defected.
The A770 is suppose to have some type of bridging with the intel CPU and GPU which is why I specifically chose the combo as I felt it was good for my circumstances. So in a few days I should get an OS installed and wondering how I can test all the features of the combo and onboard GPU to make sure everything is working the way it is suppose to or if I need to return the CPU.
Is there any programs that can do this kind of testing?
The MB did have a pin bent, it has some splotches on the conformal coating which is odd, and some weird grease like spots on it. Some of the screws for the M2 heatsinks also look used. So I'm not sure if I head a refurbishedboard or not.
Any ideas?
Update: I had a DP to HDMI adapter and just tried it and it worked so it is almost surely the HDMI port on the MB ;/ Although if move the HDMI to the DP poor it doesn't recognize the change. Maybe there is a short or something when connecting the HDMI. This of course doesn't explain the flickering and I haven't checked to see if it still does it using the onboard GPU.

- It is likely not the A770 but I do hear there are issues with it. It could be just some incompatibility with memtest but given how it did a similar flicker in the bios I think it is more hardware based.
- The onboard GPU should have worked. I think once I get an OS installed I can test it out but I'm concerned about not being able to get output. I specifically bought the K just so I could get output in case the A770 went bad but it's failing. I haven't tried the DP connector though.
