DVD Drive detected but can't play CDs/DVDs in Windows 7 64-b

I recently upgraded to Windows 7 64 bit and used my DVD drive to upgrade.

My drive was found by windows and was displayed under device manager but I never checked to see if it actually worked in windows. I then installed the program SPTD 1.60 (SCSI-Pass-Through-Direct 1.60) and after that, my drive showed up with an exclamation mark in windows. This program is required for virtual cd-devices (daemon tools).

So I uninstalled the drive and restarted and it found it again and installed proper drivers. BIOS also shows the drive as well.

However, I am unable to play, view, or burn any files when a CD or DVD is in the drive and can't figure out what the problem is. Whenever I put a disk in, it just spins and can never be read. Whenever I try to burn, Nero just stalls while "checking disk."

Windows shows the drive listed as the following: _NEC DVD_RW ND-3540A SCSI CdRom Device.

The drive is a NEC ND-3540A dvd burner so the listed is correct.

I have also tried the trick to make digitally unsigned drivers alright in windows and also taken off windows burning feature but nothing seems to help.

I uninstalled the SPTD program with no luck.

System Info
Motherboard = GA-P55-UD3R (updated to most recent bios, F4)

What is the problem and how do I fix it?

". This program is required for virtual cd-devices (daemon tools)."

I've lost track of how many times daemon tools created issues. But it is gone.

Try OTHER cd/dvd recording software like CDBURNERXP (I use it on 7), IMGBURN and DVD FLICK. For DVD and CD playback try VLC PLAYER.

-> I learned my lesson on prior OS upgrades. Ready?
1. Clean install if possible.
2. If upgrading, uninstall EVERYTHING you can. Including firewalls, anti-spy, anti-virus, anti-anything along with anything else I can uninstall that I can install later.

I missed what version NERO you had but uninstall that again and try the ones I use today.

Yes, the drive fw is the latest one and was the latest even before this happened. Any other ideas?

Got it to work but now it is really slow

In reply to: Yup

Ok I tested it out in another computer and it was working fine. When I put it back in the Windows 7 computer, it now detects DVDs fine. The only problem is that it takes 3-4 minutes to detect the files on the drive and play them. It runs extremely slow...anyone have a resolution to that?
