PC not stable, game freezes :(

My Current Configuration is

Phenom II x4 810
Asus M4a78T-E
Corsair XMS3 1333 2x2GB
Corsair vx450
Seagate 500gb HDD
Circle Cosmo Red
APC 650VA
LG w2243t Monitor


There is a strange problem. when ever i try to play GTA liberty city at resolution greater than 800 x 600 the screen freezes. I notice that the machine is still on, but the Monitor Goes into power saving mode.

when i Press Alt+Ctrl+Del and Alt+Tab sometimes the Screen appears but wierd with black spots.

This problem occured with zoo tycoon 2 but with installation of ATI catalyst the problem disappeared.

I have not Overclocked anything running the Configuration with default Bios settings. PC probe Suite shows me 42-47c for Proc and 42-43c For MB.

plz help..ASAP

Get driver update for graphics adapter if possible buy addon graphics card like HD4770/GTX260 according to your budget.

Its clearly a graphics card issue. Try playing other games and check if the problem is there with them as well... Try updating your graphics card driver and still if it doesn't help then I guess you will have to go for a replacement if in warranty.

i tried installing latest ATI catalyst for XP
PC seemed to be working with no problems
Next day the same thing occured..

i searched googled and was shocked to see this board having millions of problems...does anyone hav this mobo and faces similar problems.. can i ask for different Mobo[gigabyte 790gx based or MSI]...what would be better..

Thnx for helping much appreciated!!
