Hello everyone, I've just bought this Digital Alliance HD 6750. 

When I play DotA, after 15-20 minutes, the screen will go freeze for few seconds and back to normal.

Then, today, it happened that after freezing for three times in a row, my screen went into black while the sound keeps going out. I have to force shut down and restart my computer back.

First time, it happened while I'm browsing and this happen

Try the card in another computer. If it still does this, RMA it.
