It would seem if you can't get into safe mode that the problem may not be a driver. You say you booted with the install DVD and tried the start-up repair option which did not work? Did you try it more than once?

If your problem was caused by you removing the sound codecs, a startup repair should do a SFC /scannow and replace any necessary system files.

Hopefully you do not have some type of virus, but it would be a coincidence if it happened the same time your removed some codecs.

Maybe you could disable the sound somehow, perhaps in the bios, to try to get into some situation where you can reinstall the drivers.
