ok well first edit your /etc/inittab to boot to console and when you do that install the nvidia drivers, and make appropriate changes to the config and type startx in console...when you get in, you'll have to install and configure a program called "wine" to play games such as half-life and programs such as "kazaa"...i think the page is
www.winehq.com if you want to read up on it.......and just to tell you half-life is capable of playing in the wine version, you don't need the transgaming verion winex to play it....
