For the past couple of weeks, my computer has taken to spontaneously halting without warning. Black screen, no response to any controls (including the power and reset buttons). Today, I finally took the thing apart to see if it was a hardware fault.
All the capacitors around the CPU are leaking their contents through the top.
I knew P4s were hot, but I didn't know they were so hot that they'd boil capacitors. Grrr. Time for a new motherboard, I guess.
