Popped 2 mother boards

[Burnman]

Okay so after installing everything except for the graphics card I got to the bios screen. But after installing my graphics card my motherboard popped and had a tiny fire for about 3 seconds right when I turned it on. Then I got a replacement mother board which did the exact same thing except this time it didn't even get to the bios. The capacitor that popped is right above the ram. Of course the pc won't start now... What do you think could be the problem here?

My pc specs are

Can I upload an image of the motherboard if so how?

If two boards burst into flames when you turned it on, I would have to assume you have a defective PSU.

Have you checked the position of the motherboard standoff's in the case? In fact is there anything behind the motherboard that might be causing a short on the board. I have heard of cases where people don't put the standoffs in and screw the motherboard directly to the case as well but I assume you're not doing that.

I think you should probably get the PSU checked out as well, I am not an electrical engineer but something that is actually started a fire isn't good.. even if a 3rd motherboard works perfectly I wouldn't feel happy about leaving it.

I'm not exactly sure want you are asking me I did use the standoffs but never screwed in the middle one on the middle row because I couldn't get it to catch on the other side
