Check the memory and/or disk.
That could be a HW fault.

Use a memtest+ to check the memory and if you have smart test for the hard disk in BIOS use that.

It could indeed be a hardware fault, and running memtest is definitely a good recommendation (Ubuntu 10.10 is nice enough to put memtest in the Grub boot menu for you).

SUGGESTION: boot your original CD in "Live CD" mode, and see if that works.

And if it does, consider mounting your hard disk and seeing if you can find anything in the error logs.

Or, if it's a new install with nothing important, consider just re-installing.

Q: Exactly what did you do before it "stopped working"? Did you install anything new?

yes i was just following this article

before this i was authentication samba with active directory , here i installed krb5-users package then the config went wrong so i just uninstalled the package when uninstalling all the packages got uninstalled.

this resulted in the above condition

i managed to installed some of the packages and get the system running again
now i am able to login to the system in normal mode but when i execute any command it gives me segmentation error

let me know is there is any other packages i need to install to rectify this issue
i dont think its some hardware fault as i have dual boot and the other os works fine

boot from LiveCD and run fsck. It might be something to do with filesystem.
