Either your problem was different or you are very lucky that it has not completely crapped out on you, yet.
YLOD is caused by overheating, due to lack of thermal paste. When there is no thermal paste to transfer the heat to the heatsinks, it will stay in place and heat the chips, thus melting the solder balls under them and breaking the connection.
Change your thermal paste ASAP if you even think you are in danger of overheating. Once the damage is done, it is not always fixable.
