Hi, I'm having some problems with my graphics card.. I'ts a Nividia GeForce GT 640.
My desktop crashes every time I start certain games, Sims 3 and Sims 4. It just shuts down after 5-10 minutes of gameplay. I've downloaded Speccy, and It's the graphic card that overheats. It's usually at 50 some degrees, but as soon as I start a game it shoots to 89-93, and then shuts down. Even on Low graphic settings.. when the temperature reaches 70 the fan(or a fan, cant see the graphic card one) gets louder, but I't doesn't help at all. Just had the computer to repair cause of this. and that it was making a lot of noise. They cleaned it out so the noise is gone, but this persists, and now the warranty has expired.
The computer is about one year, and the sims 3 worked fine last fall, even on high settings..
Hope someone here can help, let me know if you you need any more information!
