My Power Supply Blew Up

Yep, last night while playing World of Warcraft I heard a pop come from inside my machine, which then turned off immediately. So I laid it down and to look at the inside and noticed the smell of sulfur. So I look at the inside and notice grey smoke coming out of the power supply.

I wait awhile, try turning on the computer again. It works. Then the grey smoke comes back out. I thought it'd be pretty dangerous to run a computer with smoke coming out of it. Damn power supplies.

P.S. I was going to try making an overclocking joke, but it just didn't seem like it'd be worth it.
