Hi,
First of all, there are more than one suspect in this scenario:
First, we need to know what motherboard, so am including a free Everest program that will tell you that:
Download and install this free program called Everest and it will tell you everything about your computer.

Second, have you downloaded the very latest drivers from the ATI website?
Third, your power supply is suspect and is probably weak for a CPU of this strength.
Fourth, Some times when you have a problem like this, the Omega drivers will help the issue;

When you get more info about your system a repost might help us to understand the problem better. Feel free to try the other drivers and see if that helps.
