Problem with LG DVD drive
I have an LG DVD drive in my present PC. The model is GH22NS50.
It worked normally until recently, and Windows 7 recognized it quite well. In fact Win 7 was installed on this computer using that DVD ROM drive.
About a month ago I installed Avid Liquid suite of programs on my PC because I needed some video editing software. It seems that during the installation of this program, a new and unsigned CD/DVD-ROM driver was installed. I know this because Win 7 promptly notified me about the unsigned driver right after the program installation. I think the problematic driver is called "ASAPI.sys", but I am not sure. I didn't pay much attention to it at the time.
Several days later I needed to use the DVD drive, but it doesn't work in Win 7 now. This is what now stands in device menager for DVD/CR-ROM drives:
HL-DT-ST DVDRAM GH22NS50 ATA Device
LYP TE3G963 SCSI CdRom Device
LYP TE3G963 SCSI CdRom Device
QPSIMR YNSPIZOH6NKD SCSI CdRom Device
All these items have a yellow exclamation mark (!) next to them, and when I look at their properties Win 7 says "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)".
I tried to delete the drivers from Device Menager, but they keep reappearing again. Also, I tried System Restore with several restore points, but for some reason the computer crashes during a system restore (Blue screen, memory dump etc.).
(Before the installation of Avid Liquid, I used System Restore several times to fix minor annoyances and it worked like charm.)
Does someone have an idea how to fix this problem?
