I have searched google and these forums for about a week trying things to no avail. I just recently installed a graphics card, but after I finished installing it, i ran into a few problems. I can put CDs into my dvd/cd drives but nothing will read. So I checked under my computer and they weren't there. So I went to device manager and they weren't there either. I went to BIOS and it just registered there was something connected to my IDEs. I read that I should try the registry editor to delete upper and lower files, but when I went there, I had no upper or lower files to delete. Is it a jumper problem? Because when I installed the graphics card, I didn't change anything besides the card itself. I dont think its a power problem since I can open and close the DVD trays just by pressing the button. Any help is greatly appreciative, thanks alot in advance.
