Also the PI has a protection device that shorts the 5V supply if it sees, even for a short time, more than 6V. This blows the polyfuse. I suspect your voltmeter is broken and completely unsuitable.
Well, I already said my multimeter was pretty unreliable for monitoring a fresh duracell 1.5V battery as 2.00V.
measuring the crystal requires at least an oscilloscope.
I don't have that kind of specialized equipment
one thing you could do, if careful, with a low wattage (15W or less) soldering iron is to re-heat (melt) the solder of the four connection points of the crystal in question X1, don't heat each pin for more than two seconds or so. This has helped others that had non- or badly oscillating X1 crystals. But its just something you could give a try. Make sure your soldering iron is well isolated, and is electrically connected to the PI if its suitability to soldering electronics is doubtful, or you could damage the PI with voltages leaked from mains to the tip of your iron. If you short the voltage with an end of thin flexible wire to the GND of your PI,, for example to the outside of the RCA video plug, or to the metal of the USB ports, or Ethernet port, then electrical damage is unlikely. Connect the other end of the wire to metal of the soldering iron that stays relatively cold.
As I don't have access to any sort of regulated soldering iron, just a common one which suits for the household needs. (However I'm willing to invest in one if that isn't too costly), the fix of reflowing solder seems comparable to common GPU problems. Have there been people before me succesful in baking the pi in the oven as far as you know? I will google a bit on it as well. EDIT: Found this one http://goughlui.com/?p=160
Also, are you sure this is the case? Or could it be a different problem? The measures that need to be taken are quite draconian to say the least.
edit: Mystery solved. I suspect my logitech g500 is demanding too much power through the pi. When I was at my parents house I tried using my moms simple USB mouse and I did not get any errors whatsoever.
