nVidia GeForce 7800 driver GS problem

    I purchased a nVidia GeForce 7800 GS and installed it on my machine.
    I am running Window XP Professional, running on 2.4 Ghz CPU, 1.25 Gig RAM.

    I first installed the driver from the CD that came with the card.
    The games run just fine, but if I try to run any video programs (Windows Media player with mpg or avi) or play a DVD the computer hangs or gets extremely slow, and the places where the minimize, close icon are located become black boxes.
    I went to the nVidia site and donwloaded the "fresh" driver from their site. Uninstalled the old driver, tried installing the new driver, but after a restart, on load the computer pops-up two errors about two missing dlls. nvcpl.ddl and nvmctray.dll
    I went through regedit, and searched from either of them, removed all, restarted the machine, still got the popup. One of the files in the Run branch kept coming back every time on restart after being deleted.
    I donwload N(asty) F(ile) R(emover), turned my internet connect off, turned System restore off, ran the program, it found one file, deleted it.
    On restart the machine had the dll again.
    I tried re-installing the "fresh" driver again, but as soon as you run any type of video programs the computer gets extremely slow and hangs.

    Can you please help me. Any help would be greatly appreciated.
    Thank you.

    When you say "uninstalled the old driver" did you uninstall from Device manager or actually remove all the old Nvidia driver/software from Add/Remove programs? If not do so and then run Driver Cleaner Pro (freeware) from here: http://www.drivercleaner.net/professional.php
    Many times you MUST remove all traces of old video drivers and software so if you had an ATI card before remove all that too.

    Also, are you running SP2 on the XP Pro?

    The missing files may just be a side effect of the install but try the clean install above before anything else.

    Thank you for replying so quickly.
    I went through the Control Panel > Add or Remove programs.
    I did it again just now, then ran the Driver Cleaner Pro that you recommended. IT found four files and deleted them, then on restart the errors with the names of the two dlls came up again.
    I re-installed the newer driver, and then after restart the system was not compaining any more about the dlls but the video software wasn't working just as before.
    I read the help from nVidia driver and it stated that there is a way to Enable Overlay through their driver's control panel. (Since the games work fine I thought maybe it is some kind of problem with the overlay settings) I followed their instructions, went into the 3D settings > Manage 3D setting > Program Settings (and I also looked int he global settings), but there is no mention of Overlay at all in the list of settings.
    I am not sure if this is the problem.
    My previous video card was also a GeForce, and did an uninstall using Add/Remove from control panel before installing the new driver.

    I looked through the setting in the nView Desktop Manager (gets installed with the driver) but the Windows Media Player still hangs, and doesn't re-draw windows when they are moved or closed. And then to close the program is next to impossible. Faster to restart the whole computer, because then all of the programs hang .

    Are you running an Nforce board? If so if and you were not careful you may have unistalled your motherboard drivers along with your graphics drivers.

    IE, you uninstalled Nvidia drivers?
