    I have just returned to discover that various pieces of hardware on my PC are no longer functioning properly or at all. The hardware is still listed in the device manager - so I thought that it might just be a case of re-installing the drivers and carrying on. However, a more detailed examination has revealed to me that this is not possible due to the fact that the DVD RW and DVD ROM drives in my machine also seem to have had their drivers corrupted.
    I have performed virus and adware scans of my PC using AVG and Spybot software respectively, however this does not seem to yield much in the way of help, as the problem has remained.
    I have also used the Microsoft support page to uninstall the DVD drive devices and then using the device manager to scan for new hardware. For some reason however, they are detected properly and then after about half a minute, they seem to disappear again. Also, I have tried to (unsucessfully) tried to edit the registry as instructed by Microsoft. Neither of these steps have worked and I cannot do a system restore as there are no previous restore checkpoints. I am running Windows XP Media Edition; below is a list of the devices which do not appear to be working:

    SONY DVD RW DW-D18A
    SONY DVD-ROM DDU1613
    Realtek AC'97 Audio for VIA (R) Audio Controller
    WinFast DTV2000 H BDA Transport Stream Capture
    WinFast DTV2000 H WDM Audio Capture
    WinFast DTV2000 H WDM Video Capture

    Lastly, whenever a dialogue box appears - my PC seems to emit a weird electronic beep (it didn't do this before hand). Can anyone help me with this? I am sorry that I can't be more descriptive and I am aware that there are a fair few problems that my PC seems to have, but I figure if I could just get the the DVD drives working, that would be a good first step!

    Cheers!

    Have you tried:

    1. Click on START button, the click on RUN.

    2. Enter REGEDIT and press Enter.

    3. When REGEDIT starts, open up the following key:
    HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class/
    {4D36E965-E325 -11CE-BFC1-08002BE10318}.

    4. After clicking on {4D36E965-E325 -11CE-BFC1-08002BE10318} you should see two settings on the right-hand side:
    "Upperfilters"
    "Lowerfilters"
    Click on each of them, press DELETE and click YES.

    Or you can download this reg file to do the same thing.

    Yeah, I have already tried downloading that and have looked inside the registry, but the values don't seem to be there. I am getting the feeling this may be a bit of a ******* virus!! Thanks for your help!

    One more thing (I am not sure whether it is worth mentioning!) - I am also running a 64bit version of Windows XP on my machine alongside this version. As far as I am aware this problem is not affecting this other version of Windows , so it would seem that this problem is contained purely within this one. Also, it does not seem to affect the wireless card (hence my internet connection is fine) or video hardware, but it has disabled my audio and tv card.
    Like I said, I suspect it is a virus of some sort; however my antivirus AVG has not picked up anything to support that.
