Question : Linux OS boot proccess failed while "Checking filesystems"

After resetting a PC  , my CentOSfails to boot up, while falling on the step "Checking filesystems".

Here is the boot proccess:

INIT: version 2.86 booting
...
Starting udev:                                     [OK]
Loading default keymap(us):              [OK]
Setting hostname test1.localdomain   [OK]
No devices found
Setting up Logical Volume Management:    /dev/hdc: open failed: No medium found
   No Volume groups found
                                                           [OK]
Checking filesystems
Warning... fsck.ext3 for device /dev/hda2 exited with signal 7.
                                                           [FAILED]
*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
...
...

1) Tried to repair with rescue disc , not helped ...
2) Running fsck in the shell , dropping the same Warning .
3) All of the data are still there , nothing seems to be deleted for now .

I have a little knowledge of the Linux partitions issue and still didn't found something about signal 7.

Answer : Linux OS boot proccess failed while "Checking filesystems"

Yes, it's possible. And fsck failed therefore (error 7)
But "Bus error" is really another story - either HW broken, or kernel image.
