Yeah, I used the Doomgaze method for a while. My computer was making funny noises. Sounded like a fan going out of whack. So I took a hammer and beat the crap out of my power supply, and it stopped for a while. Later, it came back. So for three months, I faithfully beat the crap out of my power supply, and then paid $65 for a new one.

Put in the new power supply, it was still making funny noises, because it was my card fan (A little peripheral that I slid in between my video card and sound card) at fault. Took out the card fan and everything is fine.

Moral of the story: Don't beat the trout out of your computer with a hammer.
