Just did a quick check on my 2630: You should get a resistance of around 100 ohms between GND and VCC, so you are really looking for a short between the power rails on your card.
A2630 + Big ram + 50mhz FPU ok?

"Power rail" would be GND and VCC. GND is "everything minus", including the screw of the metal back plate. VCC is the 5V rail that goes to all active parts of the card. The "teeth" are called "card edge".
Since this is a multi-layer card that has the power distribution layers outside, you may be looking for a short between the top and bottom layer, which might be caused by ripping out one of the RAM chips too fast, by over-tightening a screw or a simple solder whisker between a GND/VCC pin and one of the power layers.
Can't say off the top of my head if top or bottom is GND, but from the position of the screw in your video, I'd expect top to be GND and bottom to be Vcc. Still, the whisker may be on either side, and it may be in a totally different position (nowhere near the RAM), as a blob of solder might have dropped anywhere on the board while you worked on it.
