Since im stuck here il ask my question.

I have a Radeon HD 6970 to mine with using cgminer on windows 7, sometimes when i start CGminer my computers freezes and i have to reboot, i wonder if anyone know how i can solve this problem  and what could cause it ?

Use the flags: -v -w 128 -f 30. Also disable the hardware acceleration on flash.

Im getting -v is not a number and -f invalid arrgument when i try that. if i use -w 128 it works but what are the 2 others and why wont they work?

I prefer 6950's

i would try GUI mining sofware it works every well. and you should have no issues with flags

if your computer is crashing or freezing up it most likely overclocking? reduce the clock speed, or increase the voltage. could also be over heating, double check what kinda temps ya getting.

I use GUI miner. Easier to use
