BSOD: Install Drivers

After I install ATI Drivers 9.4, or Realtek High Definition Audio Driver 2.27 or even drivers from windows update for my TV card. Every time I change drivers I get a BSOD, not after install but after the installation I make a restart and BSOD happen (after the logo of Windows 7 and before the welcome scream). I could get in, in Safe Mode and try the restore and sometimes after that i can get in again in normal mode, but if i make a rr again, it goes to the same thing.

If someone could translate that for me, it will be great. I already try google it, install drivers once in a time, install the SO many times, but still can't isolate the problem of the BSOD.

In Windows Vista everything works great, but in any build of 7 give me problems.
