Right, I've weilded my multimeter

Voltage on either of 5V pins = about 4.56V
Voltage on the 3V pin = 0.58V (but about 3V on the outer pin)

Resistance between all 3 >1000 ohms

So what's the diagnosis?

EDIT: On close inspection of the MAX1631 chip I can see this:

Could it be causing a problem or not? It looks like it's just a bit of solder so I would have thought if it was going to cause a problem it would have done so years ago? And how best to remove it if you think it could be causing a problem? And could it have done some permanent damage?
