Problems while building, went kapoot.

Well I was building a computer, I went to install the CPU and the heatsink, and I hook them in. I plug in the power supply, I flick on the switch, my lights turn on. So I shut it off. I then try and power it up again. And... Nothing.

Oh noes!

Make sure your power connectors are the right way around on the motherboard. Ground your computer. Switch the PSU off from the back. Reset your CMOS and put everything back together. Ground it again before you try to turn it back on.
