I remember shipping a motherboard we called the "Red Green" motherboard due
to doublesided tape holding a crystal to the board. (I know, it's not duct
tape, but it's close enough for me)

That board encountered odd problems due to what we felt was an inadequate
ground on the canister of the crystal. In fact the "Red Green" board did
prove itself over time in corporate environments, and the odd problems were
finally attributed to operator error.  As to degrading over time, well, we
all degrade over time.  I'm degrading as I write this. ;-)  The real
question is whether the board will fail prematurely.  I am not overly
sympathetic to people who have problems with 5 year old hardware, but
sympathy increases as age decreases. A 3 year old board should (that's
_should_, and not _will_) be a reliable piece of hardware. A 1 year old
board should take anything you can throw at it.

Check your power supply.  Not all power supplies are created equal, and they
almost always have components that degrade over time, including fans and
electrolytic capacitors.
