Did you uninstall the old driver before you inserted it? Also did you install the latest drivers after?

If it a heat issue that the gpu fan not spinning up to speed to keep the gpu cool. Try using msi afterburner to set a fan profile to max out the gpu fans at 50 c. If it still locks up..try taking te side panel off your pc to see if it an air flow issue. some mb and video cards had bios bugs. Check to see if your motherboard vendor drop any bios updates.

Hey, its a common issue.

Uninstall all previous graphics drivers and any software that came with it.

Then, use Drivesweeper or something to make sure there arent any redudndant problems.

Then insert the CD that came with your card, or simply download the latest drivers from ATI website and install that.

Download Catalyst ssofrtware from Sapphire/ATI and in the overclock tab make xsure you set fan profile to 100%. During gameplay, monitor your GPU temperature to make sure it does not exceed 60-70C.
