I installed Nero burning ROM, but afterwards, my PHILLIPS dvdr 16lsCD/DVD ROM drive and my DVD/Writer both disappered from MY Computer. Device manager says their there and I have the error code 41 also. I uninstalled Nero in hopes of a recovery of my drives…but nope. In the process of hunting, I checked my ASPI drivers with a program called ASPICHK and it said the drivers were incorrectly installed, so I reinstalled and rebooted, still no CD/DVD Drives So if any one knows what reg entrys I’m looking for, what my problem is, I welcome comments from one and all.
Sounds like an upper/lower filters issue. I’ve done it a bunch of times and it’s always worked.
