Random thoughts: it is possible that the video card has 'died' on some
level -- such as its on-board memory is developing errors or some
component has shifted out of spec, etc.  Does the card have a fan on it
(some video cards have little processor elements with heat sinks AND
fans).  Is the card covered in a thick layer of dust (and thus not
being cooled properly)?  Are all of the case fans on this '5 year old
box' working?  Is the PSU still in spec?  Is its fan working? I'd try
cracking the case and have a serious visit with Mr. Vacume Cleaner. 
Then powering it back up (with the case cover off) and checking to see
if the fans are *all* working.
