Two common problems, Todd.  First being the memory card it yours has one, has 
settled into the socket, lift it about 1/8".  I'm told that some boards have 
extra long legs and can touch or short on something.

Second is corroded contacts on the gime chip and its plcc socket.  Do not try 
to pry it out of the socket as that will crack the corners and half the 
contact pressure will go away forever.  Get your self a "plcc" puller, the 
shack used to carry them but haven't looked recently, and apply it to lift 
the gime chip out of its socket.  Carefully note that one corner of the chip 
has a bevel instead of a square corner, and that the socket also has a 
matching beveled corner.  When re-installing the gime later, these bevels 
must match as that is the way you keep the chips numbered pins connected to 
the same numbered pins in the socket.

The chip is waterproof for long enough to take it to the sink and polish up 
the contacts with  some toothpaste and an old tooth brush, then rinse well & 
park it on a terry towel to absorb most of the water, and finish drying with 
a hair drier after you have used a used toothbrush dry on the socket and 
blown all the debris that dislodges away.  A wipe of alcohol (not rubbing, 
use paint thinner alcohol, it is much drier) with a paper towel on those 
contacts would be good too.

When everything is dry again, locate the bevels & turn the gime till they 
match, and press the gime back into the socket.  It should sit with its top 
nearly flush to the top of the sockets plastic, and that may take 20 pounds 
or so, so be sure and support the PCB on something solid.

If that doesn't restore it, then Mark M. (Cloud9) should probably  be the 
next one to look at it.
