Okay, N3051M got in there while i was typing my reply. The first part of what he said i already explained that. Seems you tried that and got no results. He also mentioned uninstalling those 2 programs but it appears you already said that you did uninstall them. I went further and explained that even though you uninstall a program you still need to go to program manager and manually delete the folder and any files left over in it, plus the fact that even when all that is done you still may have to go and edit out entries in the registry that pertain to these 2 programs you deleted.
But before i gave more advice , I just wanted to make sure what you did have on your system before going further.
Any, yes, it could be that the cdrom drive is kaput, finished, dead. But im not sure of that quite yet, lol. Dont forget these drives cost under a dollar to make in the factories overseas, with the parts costing under a dollar as well, so they arent that well made, especially the cheaper ones but even some brand names as well. I received a dead cd burner from newegg.com once. They have a good name and a good rep but i just got a bad one. Of course they replaced it, but it shows you that they can be bad right from the factory. And they can go any time, in one day or they could last 10 yrs, you just never know with these drives, same goes with hard drives too. They are cheaply made as are most other computer parts. Its only the research that costs money in the computer field, not the actual parts. Except for cpu's and perhaps some high-end vid cards, cpu's especially are a bit more costly to make than most other parts.
All this rant is only to tell you that these parts do go bad and dont always last that long, so you could have a bad unit.
Best to try it in another persons computer. Even if the cdrom drive is bad it very likely wont do any damage to another persons computer, so its reasonable to ask a friend to do this for you. I have done it dozens of times, actually hundreds.
