need help getting sound working and ati radeon hd 3450

[Painwarlock]

im very new to debian and i want to install all video drivers correctly and get things set up i did a net install and i followed guides to make my ati radeon hd3450 card work (worst thing i could ever do) i screwed up the install i made a back up but it didnt show a back up and when i rebooted my xorg file was empty when i nanoed it after nearly throwing my computer at a wall like the tourrettes guy trys to that beer bottle at the bird in the bird in the house episode (xDroflxD) i thought i would come to this universal forum to ask for help on how to install debian correctly

So you have installed debian once then install it again.

If you have a debian installation and you just screwed up the xorg.conf you need to reconfigure it.

dpkg-reconfigure xserver-xorg

for video card:
download the newest driver from ati.amd.com
and install your kernel headers

apt-get install linux-headers

if the package does not exist find some similar one
use

 apt-cache search header

after an

apt-get update

then use the graphical installer of the vga driver.
