Sorry, I didn't mean to be vague. It basically comes to a stand still. It is slow...almost to the point of shut down. If I try and click on a program, it certainly won't load it. If I already have a program open, such as CS4 and or Bridge, it is unusable, won't load images. This only happens when using the DVD multi drive. Also, many times the drive won't open when I try to use it. And it seems to have a high refusal rate of DVD's that I try to format/burn. It will say that it is unable to format disc. Could the drive simply be bad?
