Hi Everyone, Can anyone please help me? About a month ago, my sister told me that just as she was about to burn a CD, Nero told her that she did not have a CDRW installed. She told me to check her computer, and sure enough, when you open up "My Computer" (in XP) her HP CDRW is no longer there. So, we went and bought a new CDRW drive (different brand). When we installed in (in addition to the other one, and not actually replacing it) Windows did not recognize the new drive either. When we went into the "Device Manager" it listed both CDRW drives, but when you click on the properties of each, it says that the Windows registry might be corrupted. So, I reformatted her computer and installed XP again. Both drives were working fine for a week, but just today she told me that her CDRW drives were missing again. Again, windows says the exact same thing as before that the registry might be corrupted. We "uninstalled" the drives from device manager, and restarted. Windows seemed to find them again as it booted up, but it still won't list them in "My Computer" because clicking on the properties (in Device Manager) still claims that Windows registry might be corrupted. Any ideas? I really do not want to format her computer EVERY time that her CDRW drives disappear.
