python, screen saver, grub

[Manuel Tejada]

I have just installed RedHat 7.3.1 in my PC compatible (Pentium III, 250 MB RAM, 30GB hard disk). The installation was fine, no error message gave me. I chose this: - Workstation Installation - No install GRUB neither LILO. Then I must to use a boot disk to start RedHat   I only do common tasks with OpenOffice.org and PostgreSQL.   The reason to post this message are three things:   1. Every time I turn my computer off, appear the following brief message: "The application /usr/bin/python has failed due one fatal error.  Segment violation" ( I did not why because I do not work with python)   2. Every time I leave my computer for a while, the screen goes black. The screen saver does not raise. I have reset the screen saver but it does not respont. (Actualy the screen saver works sometimes but most of the time does not.   3. I would like to use the boot loader GRUB but I do not know how to install it.   Anaybody want to help about theese three matters?
