Any idea to tell what just burnt up in my computer? I was trying to get the power switch connected to the motherboard(one of the least intiuitive things I've ever seen), finally think I get it right, and turn it on. It immediately powers off, followed by smoke coming out of the fan port located under the bottom side of the motherboard and a horrible smell.
So far as I can tell, everything else was connected properly. As long as the power supply, the hard drive, and those goddamned power pins are okay, everything should be fine since I just acquired replacements for everything else. It burned up while trying to put the old setup back together.
EDIT: I figured out what I did wrong, I accidentally plugged something somewhere else where it most certainly does not go. Unfortunately, I still don't know what is destroyed. While the mobo lights do come on when the power is connected, actually turning it on via the front power switch does not work.
EDIT2: Narrowed it down to either the graphics card, or the part of the motherboard where the PCI and PCI-e slots are. Probably the latter, the graphics card shows no sign of burning, and none of the fans on that part of the board spin. The WiFi receiver in one of the PCI slots is supposed to also light up, which it doesn't, and changing PCI-e slots with the graphics card did nothing.
Either way, there's no point in worrying about it anymore. All I'm waiting for is a IDE-to-SATA adapter(for the old hard drive) which I've already ordered, then I can put all the shiny new stuff in. And hopefully not screw that one up.
