You could try "breadboarding", as said above use only one stick of ram in A2 and with that just motherboard+cpu+gpu, see if it will boot.
Anyone around you who has maybe another gpu to test with? Or psu ....
Its been a few days and I've tested a few things. Nothing is working. I have 2 gpus they are both tested and working, tested the 2 sticks of ram they both work. The 2 drives 1 ssd and 1 500gb hdd both work. After resitting the cpu and repasting, I was getting the exact same random codes and booting issues and nothing is working. after about 24h now I'm getting a "00" or "D0" code which I think is a cpu issue. But I cant test that or the mobo without another pair thats compatible. So I'm going to risk getting a cheap compatible mobo and test it out, and hope it works.
I've posted about this mobo/cpu combo before as this has given me issues before. Like if I keep the pc off over night in the morning it doesnt turn on, for some reason i suspect due to temperature or humidity. I have no idea if this is a thing but its defenitly something weird. But I have no clue how to test this issue.
So if i press the ON button if nothing happens I just wait a while sometimes hours and the pc turns on by itself and it usually rocks on after that. But recently the same issue happens (not turning on) but now theres no boot. Black screen and now the "D0".... So if theres anyt hail marys I can try here, I'm all for it!
Thx all for the help
