Hello guys so last I was upgrading my pc to the new i5 13600kf and when I first completed the build, I booted up normally and even did a benchmark (https://www.userbenchmark.com/UserRun/57048103). After this, I realized that I had forgotten to plug a case fan and so I shut down the pc but I mistakenly pressed restart and the restart was taking a while so I forcibly shut down the pc(stupid I know). When I plugged the fan in and tried to start the pc nothing happened, I looked inside the pc case and saw that when I pressed the power button, the DRAM and CPU debug light would both flash for a millisecond and that's it. I contacted AsRock and they sent me a list of things to test out but to no avail. I rebuilt the pc inside and outside the case multiple times making sure nothing shorted and everything was perfect but it always did the same thing. I soon found out that all my fans and light would work if I did not plug my cpu 8 pin power but the pc wouldn't boot obviously. I have no clue what happened or how to fix this but I am asking you guys as my last attempt and will return the motherboard for replacement tomorrow if I don't find the problem here since I think the motherboard is the issue.
