please help me about this matter..

1. gdm is not a boot loader. It's a part of Gnome/XWindow system. You do not need to reinstall boot loader to correct gdm config. Try to look at your XWindow configuration.

2. If you plan to completely reinstall the system and did not created a separate partition for your /home directory, putting your root (/) and /home directories on the same partition, probably the whole partition will be formatted, destroying the user files. You must make a backup first.
If your /home directory is on a separate partition, you can reinstall the system with no problem. In any case, backup of your files prior to reinstallation is a good practice.

If you tell what distro are you using it will be easier to give you more specific advice.

Good luck.

Well, it's not the same the bootloader and the X greeting app.

Bootloader gets PC control from BIOS and is the "program" that will load your linux on your machine.

Greeting app is the one that takes your user name and password and drives you to KDE or GNOME.

If gdm is crashing, you can try with kdm or just xdm.

And no, if you update your bootloader your home directory will rest as it is. Don't care.

Have fun!

Edit:
Wow! That's efficiency, dr_agon!
But upgrading a single packet is not reinstalling system...
yum seems redhat or mandriva, perhaps?
