@xXtjaXx2000 If you haven't used the computer for some time for gaming there may be dust in the video card fan. You really need to check the computer for dust in all the fans. If the fans seem to be working make sure they are able to turn at proper speeds. The fans should turn free (while the computer is powered down). If there is the slightest resistance either replace the fan or access the shaft bearing and give it a small amount of sewing machine oil (light grade machine oil). Sleeve bearing do this over time when the oil gets contaminated and gums up. While oiling the bearing may work for a while I recommend replacing the fan. The fans are usually cheap and must are usually easy to replace. A can of air would be good to blow the dust out of the heat sinks. Make sure there is nothing touching the fan blade.
