A few months ago late one night, the old Cat was sitting around spawning some code and heard a sound in the room.

Nothing presented itself for visual inspection, so we took a look about - and found nothing.
The noise was like a plastic ruler being slammed on a desk hard.

It happened again last night, and when we observed the system the main video display, a geforce 8800gt, was filled with artifacts. 3 electrolyte capacitors had blown...not leaked, blown!

Word to the wise: if you are ever computing late at night and hear a snap like a good cap gun - check your caps!
