Windows 7: DVD & Webcam drivers not recognised

15 Jul 2017   #1

Windows 7 Professional 64-bit
DVD & Webcam drivers not recognised


I recently bought a secondhand PC from ebay - a Dell Vostro 230, running Windows 7 Pro 64-bit. All it had on was the Win 7 OS, so I set about copying files, downloading the programs I use etc.

I have a webcam that worked fine on my Windows Vista PC (Trust WB-3400T webcam), so I plugged it in and inserted the CD with drivers etc on it into the DVD-RW drive (HL-DT-ST DVD+-RW GH50N ATA).

The DVD worked fine - the window opened on the screen and I clicked to install drivers - then I removed the disc and thought that was that. Later, however, when I downloaded Skype, I noticed that the camera wasn't working.

I opened Device Manager and could see a '!' on the webcam, so I set about updating drivers - but with no success. At the same time, I noticed a '!' on the DVD drive listing as well. I tried to use the drive with a couple of different discs, but nothing was visible on-screen. I tried updating the DVD drivers, again with no success.

So, it seems that my DVD was working fine, but after I installed the webcam software, neither the DVD drive or the webcam are working.

I have since spent about 36 hours Googling the problem and trying countless methods of downloading new drivers, re-building the INFCACHE.1 file... you name it, I've done it. I even tried doing a system restore right back to before I inserted the webcam disc, but there was an error that wouldn't let me go that far back (a file it couldn't access, or something).

The last thing I did was to do a thorough uninstall of all the webcam stuff, then reload the DVD driver, but it is still not working.

I feel sure it can't be a hardware fault. It seems unlikely that both would fail at the same time. I thought it might be some kind of conflict - but then uninstalling the webcam didn't help.

Whatever I do with drivers on Device Manager, I end up with a message like the one attached.

Can anyone help me get my DVD and webcam working?

Many thanks.
