Is there a way to configure my computer to run a..

If bash is your default shell you can add your script to the .bashrc file in your home directory. This will launch that files whenever a shell is opened as your user, which means that the script will also run whenever a new terminal is opened.

Or you you enter the startup options for the user account to tell it to run the script whenever you login through the gui.

Another way to start something after your login is to use .xinitrc file, if you use XWindow.
.xinitrc is executed only after a graphical login (XWindow), .bashrc is executed even if you login from SSH.
Is up to you to decide where you want to add something, if you don't care about a remote login you may use .bashrc

I differentiate it because I login to my work desktop even through ssh, something is run automatically when I login with a remote shell (shell customizations and so on), something is run when I login from the XWindow console (Firefox, Pidgin, Evolution for example)
