PC blue screens a second into XP loading

[hitharder]

my computer get a blue screen a second after the XP loading screen has appeared and restarts os quick i cant get a error number and it does it over and aover again.
to make things worse i dont have my original XP disc and cant find my keycode.
it happened after a driver update for my GFX.
i havent tried safe mode yet as my g15 wont allow me to select it in boot up.
i also have read on other forums people have had similar probs and not worked in safe mode.

when you start your computer kepp pressing f8 while the computer startup you will get a menu that say a couple things click on the one that says disable automatic restart. Next time you will get the blue screen note down the error and post but if you say it started happening when you installed the latest update for your drive then use the method above but insted click on safe mode and rollback the drive or unistall the drive also befor you try any of that try the method above but click on the one that says last good known configuration
