luwkwul,
I've read all the messages in this thread very carefully. Are you certain that the problem with your CD players not being recognized started only after using msconfig? I'm asking this because, assuming that you canceled all the changes, your system should be working the same as before.
I think that it's much more likely that the CD problem began when you changed your motherboard drivers. Here is your post right after you did that:
Ok here is my new dxdiag dump... and my computer is running slower after I tried to install some new drivers for my motherboard. The game has the same problem btw, with the drivers I've installed.
The part about your computer running slower suggests that something changed for the worse. Also, the fact that plug 'n play couldn't get the drives back suggests that the problem lies below the operating system level (in other words, if your motherboard no longer recogizes the devices, then neither will Windows).
What do the others who are helping think about this analysis? It seems to me that the motherboard upgrade has to be rolled back. Perhaps from some original discs that came with the system?
