You gave VERY little information so only a wild guess can be given

if a gui is being used then the /tmp/.X0-lock might need removing

Also centos 5.5 is unsupported you NEED to upgrade to the ONLY supported 5 version
CentOS 5.7

you are two versions out of date .

If you can, I would use some other LiveCD to actually recover your personal files and move them to a backup device prior to mucking about with your OS.

After that, I would go with John's suggestion and install the latest version of your OS.

I could download Ubuntu Live CD and tried to reboot the system with it. Originally my system was installed with Windows 7 and Cent OS. I am having booting problem with Cent OS. Now I am trying to boot with Ubuntu Live CD. In the option, "TRY UBUNTO", I could view only Windows OS files but not the Cent OS files. Can any one help in this issue? The matter is most urgent.

had mentioned. Well the simple steps to do, if you need to back up your data, please, find a LiveCD such as Ubuntu, Fedora, CentOS etc., boot with that CD. Once when you get into to the option "Try Ubuntu ... Fedora ... CentOS" based on the distro live cd you use, get to the GUI. Thereafter, just copy the files from the HDD that has your problematic CentOS, to another medium, either a HDD or a USB drive, based on your data size.

Try this and you'll really appreciate yourself for the effort.

Best of luck.
