I am having this problem on my computer and I can't find a definite solution at this point. I have vista on my computer and I think the problem was caused from using Nero. I am also having problems with clone dvd. I am not very computer savy, so any help woul be appreciated. I have an Atapi DVD A DH16AYH. I tried to run forceaspi, but my computer would not let it run for some reason. I have removed nero and used their download to clean up my computer completely of all the components. Thanks.
