The 6970 is a very power hungry card so it's the likely issue. Try unplugging any non-essential powered devices (extra hard drive, DVD drive etc.) and try one of your games out again. That may not free up enough power to see any results.

I suggest a single rail 750-800W PSU if a replacement is necessary. It would probably be more than you need, but it's better to have it and not need it rather than the other way around. I say single rail because most PSU's can't provide steady 12V power through multiple rails.
Nailed it.

You don't have enough juice for that card, please upgrade and try again.

if your running a cheap PSU, your probably only getting 77% of that 600w.
