I have tried to do this, after accidentally deleting my sound system as you did, and it shows me the same error message. I have tried restoring several times and the computer says it is unable to restore due to missing programs (which it should fix, right?
??) anyway, I have tried downloading soundmax and it says i cannot download the drivers without the program and vice versa. I talked to a tech support senior and they said it is going to cost me a minimum of $140 to fix what I have done. I want to call BS. Any tips or hints?
