So... I just fried my CPU. I had the water cooling pump daisy chained behind two case fans. Turns out that when I plugged the case fan back in earlier, one of the pins fell out of the plug. I didn't notice until the computer shut off. I let it cool, and it managed to boot, but froze after about 5 minutes. Now it won't even post. UGH. I guess I'm gonna get a sempron or something to hold me off until the summer. I'm going to be permanently switching to air cooling too.
EDIT: Crap. I picked up the motherboard to find it sitting in a pool of coolant. It seems the heat cracked the waterblock and made it leak all the coolant out.
