I think your mother board graphics driver does not support centos6.the better solution is to use another linux varient.If you need centos,you can use centos 6.2.

Please replay the result if you successfully run centos 6.2

The generic video drivers that ship with CentOS/RHEL don't normally support many resolutions. You'll have to install the drivers for your specific video card.

is cent os 6.2 support my card? –  KIRAN K J Jan 28 '12 at 12:12
How can I possibly answer that? You haven't said what card you have. –  MDMarra Jan 28 '12 at 14:18

Please also look at "xrandr" output to see the supported video resolutions.

Giving an example of the output that you might expect to see would improve your answer. –  Iain Feb 4 '12 at 15:08

Sometimes you can do Ctrl-Alt-<keypad plus key> or Ctrl-Alt-<keypad minus key> to change the resolution on the fly.
