It happens also on FEAR2 and other games.

My pc specs:

CPU : e8200
2GB RAM DDR2 800mhz
550W
Mother board: Asus P5KPL

I probed the card in another PC and works fine.

Thanks

What make/model PSU? They are not all the same. Did you connect all required PSU connections.

Have you installed the latest Drivers from ATI and made sure that drivers from the old graphics card have been completely removed

But in many games like crysis,fear 2 the textures have low quality and the colors appear.

FPS rate is good.

What make/model PSU? They are not all the same. Install Speedfan or similar to monitor GPU temp. Check GPU cooling fan is spinning. Speedfan can also chart th value of 12V rail. If your PSU is good quality, 12V rail stays constant and GPU temp stays under 100C, you have faulty video card, return it under warranty.

GPU Fan is spinning very well. I can change the speed with the ATI drivers.

The GPU temperature(while playing is under 66ยบ).

Then it's either the PSU or the graphics card. Put Speedfan on Chart tab and display the 12V rail. If the 12V stays flat while stressing the card, get it replaced under warranty, it sounds like faulty memory on the card.
