I bought a HD9750-DC2T-3GD5 back in March and have been having some weird issues with it ever since. I never overclocked it yet, just left it on the default settings.
It started with the fans being at 100% whenever I played a game, to the point where I was selecting the lowest graphic settings in a game like Diablo in order to play it without having to wear headphones just to hear it.
Now my computer seems to be crashing randomly whenever the graphic card is taxed at all, even something as simple as a flash based game on a browser. So I started investigating the issue a bit more.
in the CCC it shows the temperature of the card at around 70c when idle, and being pushed over 100c with any kind of load and that is when it dies. Here is the logs I captured from GPU-Z

Tried emailing Asus Support, but haven't had much luck so far. They just replied saying it's normal to be 70c when under load, which isn't what I said at all.
