How to recover from mode
 

I have FC3 machine on which I am using xampp services. I login @ my machine with my own credentials as ip is 172.25.15.55. This is a GUI interface.When i logged in,It prompts error "You have logged In. click here to login". This I found several times from last 2 weeks. My resolution actions for this just restart the machine. Today I have done the same. Before restarting I always do restarted the services of Apache but after this the page of 172.25.15.55 not even open, I found error related to Read only file system.As i see it on putty machine.

I leave this and restarted the machine as I always do. Now when I restarted the machine error “ext3 -fs error (device sd1) in start_transaction: Journal has aborted". It is prompting continuously until I did not hard boot machine. When I restarted machine again, it is coming into grub mode. Now I don’t know what to do.

Welcome to LQ,

Sorry to announce you that your disk died. But first thing first, FC3 is 8 years old, it is end of lifed and full of visious security issues. Fedora is supported for 18 months after each release and the current one is Fedora 18. Once you get a new hard drive, please install a supported Linux distribution. If you plan to install something and leave it alone for a decade, use CentOS, as it will get security update until your next disk will die.

Hard drive can "die" in a few way. One is plain aging, where the disk run out of emergency sectors to replace the broken one. This is probably what happened to you. If you had enabled SMART disk monitoring, you would have been warned many months prior to the fault.

Boot from a CD/DVD into rescue mode. Mount your hard drive, and run "fsck -a /dev/sdxx" (where the "xx" is whatever disk device partitions you have), to try to recover the journal from improper shutdowns. That MAY work. But really...FC3 is very, VERY old. You would be far better off loading a current version of Linux and restoring your data to the new system.
