The 8800 is infamous for overheating with the fan being controlled by the Nvidia driver. Nvidia drivers usually run the fan at only 33% of its maximum speed in order to keep the fan from making noise. Riva Tuner or EVGA Precision programs can be used to increase the fan speed. I run my 8000GT at 50% fan speed. Case cooling and cleanliness are also important. Odds are after 2 years you have a lot of dust inside the case and inside the cooling fan and heat sinks on your CPU and your GPU. They will need to be cleaned, but do not blow air on the fans and allow them to spin. Doing so can over speed the fan and damage its bearings and the rotation of the armature in the motor will generate electricity that can back feed to the motherboard or PSU.
Good case ventilation is also important. I have an Antec 900 case with two 120 mm fans in the front pulling air into the case, a 120mm fan in the back and a 240mm fan in the top of the case acting as exhaust fans. You want to keep cables tucked away so they don't block airflow through the case.
