Smoke and burning smell from PC

[Comja123]

So I've been having some trouble with my PC. It crashed while playing a game and wouldn't boot since but would turn on. So I done some research and I heard a lot about it being the PSU, tried a new PSU but that didn't work.

I then tried a new graphics card and that didn't work either.

So that lead me to believe its the motherboard, I tried a new one but now my computer is smoking and smells like something is burning. Nothing is hot to the touch though.

Any idea what the heck is going on?

I suggest you leave the case open and boot it up. That way you can physically see if anything is smoking.

Also, get something like CPU-Z and GPU-Z to monitor hardware temperatures while in idle and load. This will indicate what may actually be heading up
