Hi, the title states the issue. I know this has been asked and answered before but both the accepted solution and authors replied solution doesn't apply to me, link at bottom...
To start, this only became an issue one day when I tried to reboot while my GTX 770 was installed with my current setup (Below).
Originally, according to my POST buzzer on the mobo it was a graphics card issue, I thought my 8yo graphics card died, so I replaced it with my current graphics card(GTX1080, tested personally before purchasing from a friend, so I knew it 100% worked)
But the same problem persisted. So I started troubleshooting, taking out my old desktop. Steps below.
Hardware info:
3600XT
GTX 1080 (Asus Strix)
RM600x
Asus Prime B550m
Primary Monitor; 4k LG usually connected by DisplayPort
Secondary Monitor; 1k LG, HDMI
I'm sure the rest is irrelevant.
Troubleshooting:
Summation:
This is a real head-scratcher...
-On the bright side, the PC still boots fine if I disconnect the DP first from the monitor, wait for the POST beep, then plug it in. But it's really bugging me that I have to do it...
Seriously any help or insight would be greatly appreciated
& I hope I answered all of your possible troubleshooting follow-up questions to really narrow down the wide range of possible problems to the problem at hand.
-I cant return either graphic card to the manufacture, but I assure you they both work perfectly on my old Intel and the previous owner's pc in the case of my new(er) 1080.
-Both graphics cards can run the furmark 4k benchmark for the 1080 and 2k for the 770 for as long as you want to be installed in either PC, DP installed or not, with no issues & no software or PC crashes.
Similar issue, though not relevant.

Secondary Monitor; 1k LG, HDMI

Troubleshooting:
- I've made a couple of switches of each compatible part between another intel 3570k pc with a working compatible motherboard.
- Neither 1080 nor 770 would boot with DisplayPort installed, (I only went according to post at this stage, so I never figured it was a DisplayPort problem)
- Swapped both 1080 and 770 into old 3570k pc and both booted with either DisplayPort or HDMI, inputted to either of my 4k or 1k LG monitors ---(So the DisplayPort/4k monitor you'd assume was not the problem. You'd therefore assume it was the motherboard...)
- I Purchased a new motherboard of the exact same make and model, b550m Same issue, this time I figured out it only booted while DisplayPort was plugged in, and I swapped MB back to check. ---(I was then pretty stumped, maybe power supply to the new board, no. swapped it out for my old working corsair 500w PSU and the issue persisted)
- For irrational fun, I also swapped out the 3600XT with a working 3600 my housemate's pc had, the ram with the sticks from his PC, still nothing. ---(Then after googling and all that, I turn to you)
Summation:
- Everything worked until one day I rebooted, I changed nothing including not changing any software or display settings.
- I tried 2 graphics cards, 2PSUs s, 2 processors, 2 motherboards, 2 monitors using configurations;
- HDMI & HDMI (Worked) - HDMI & DP (Not Working) - DP & HDMI (Not) -DP 4k (Not) -DP 1K (Not) -HDMI on either 1K and 4k Monitors only (Worked).
- On the old PC, It boots fine with a DP connected with both graphics cards in any configuration.
- On the new setup it suddenly doesn't, regardless of swapping out every conceivable part.
This is a real head-scratcher...

PC Won't Boot Without Removing The DisplayPort Cable And Un-Plugging It From An Outlet.
The title basically tells the whole story. Also i noticed whenever i don't unplug the displayport cable and power cable the Ez Debug LED turns on and shows that the GPU is having some kind of issue. This also happens with my other GPU. Specs: MSI Z270 Gaming M3 i7 6700k H80I V2 EVGA GTX 1080...
