ok.. IDE you have 2 devices per chain normally. master / slave... when you put in the new one, was it replacing the old one or in addition to?
if it was replacing it , it should just be a case of having the same jumper settings for the old / new drive.. I think if I recall they normally come setup as slave.. haven't installed one in a while.
as for the graphic card.. if your not using your old one you can disable it in the bios , like Ed has said as it might be wanting to take an extra IRQ.. and share.. you can see what's sharing and not in the resources , off device manager if you view by IRQ. (I have to disable networking or else it interferes with timing)
are you using a specific package for burning, some will say to turn DMA on if it isn't already. The first thing is to see how it picks it up in the bios in the standard setup, a lot of machines are just setup to auto detect.. that will give you the correct figure of IDE / sata ports, regardless of what windows said.
personally I would remove the new graphic card... take a screen shot of the IRQ's and see what changes after you add the card..
but get the dvd drive working first, or try it without the new card installed. See how it reacts to writing, if thats what your having the issue with.
edit :
if you post the make / model of the mobo (use CPU-Z to find out) then it would probably be easier
http://www.cpuid.com/cpuz.php edit again b4 I go :
try running the registry tab of this
http://www.filehippo.com/download_ccleaner/ when it asks you do you want to backup ya registry say yes.. but it's never messed up on me yet.. not the point though.. might find some odd entries in your rego to fix.. rescan until zero or near zero.. reboot.. see if that helps
