Getting BSOD from flash

Guys, I am getting BSOD from playing flash. it happened a few times already. I am able to videos in Silverlight or play videos in media players without any problem.

Following is my setup:
Win 7 Ultimate
Core i7
8GB Ram
64bit OS

BSOD blames your ATI Radeon Drivers (TDR error)


Usual causes: bad driver,overheating, faulty GPU

Uninstall the ATI drivers including Catalyst and use Driver Sweeper to remove leftover ATI files
Guru3D - Driver Sweeper

Then reinstall the drivers http://ati.amd.com/support/driver.HTML

Code:
