OK, put the power limit up by 5 and then try running the game again. If you get the same error then put it up by another 5, so that is a total of 10 and then give it another try. If it wont let you put it up in fives then just go straight ahead and put it up by 10.
If you still get the error then leave the power level +10 and then put the core clock down by 50 and the memory clock down by 100 and then give the game another try.
If the game works after any of these changes then we know it means either your card is being underpowered and so needs a voltage increase or it is overclocked too much and needs to be downclocked a little.
