Hello,
I have tried all the steps mentioned for POST and I still haven't solved my issue. I've been building a custom gaming pc and once I had connected all the components and connected the hdmi to the motherboard, I powered it on and there was no display. After a few seconds there was some smoke coming out and a strong smell I then panicked and switched it back off immediately, I tried to find the source of smell and it was one of the 2 rams I had connected. So I took that ram out and found it was burnt. As there was no display I connected the hdmi to my graphics card and on the next boot there was a display. After that I wanted to check if the ram slot was the problem or the ram itself so I connected the still functioning ram to the ram slot where the other one got burnt. Again there was no display but I turned it off immediately in fear of getting smoke again. I then put the functioning ram into another slot and there was no display again and the computer was on.
My question is, where is the issue most likely to be as described? I've gotten a replacement for the motherboard as it was not displaying anything even with working RAM and also a replacement for the RAM but I fear connecting them again in case the issue is in the power supply and not in the motherboard or ram. So should I get a replacement for the psu as well to be on the safe side?
The specs in case they're needed:
Psu: evga 650 gq - motherboard: z170 pro gaming - ram: 2x8 gb hyperx fury

Yes, that could be a problem too. If RAM (or any other component) is not properly seated it's same as if you remove or plug in a component while computer is running or under power. That in most cases results in screwed component or MB.

So should I connect the new motherboard and RAM I got as a replacement without changing the psu and I should be fine?
