Question New GPU, Freezing game but can still hear the game's sound

[NoobAtTechStuff]

Recently i just installed a new cheap AMD HD 7670 but when i try to game the game just freezes but i can still hear the game's sound! This problem didnt occurred when im still using my crappy integrated GPU.

Things ive done

• Reinstalled gpu's driver (both from the website and from the gpu's box CD)
• Checked my PSU compatibility with my GPU
• Cleaned my GPU a little bit
• Prayed
• Updated my Motherboard

Please help me since i dont wanna waste 50$ for a gpu, thanks in advance. (Sorry for English)

Intel G630
AMD Radeon HD 7670
4 GB of ram
