Lem,
Okay i'll explain: I have an ECS K1N SLI motherboard (NForce4 chipset)
with an Inno3D GeForce 8800GT dual head video card. Connected are:
Hitachi CM752ET 19"CRT RGB out to RGB/DVI adaptor
Samsung SyncMaster 172x 17" TFT DVI out
I had to change the motherboard after a failure and after I did so noticed
that the 8800GT fan was constantly running at full speed. As I am not a
gamer this was very annoying so I downloaded the latest certified NVidia
driver. I found that NVidia had changed their Control Panel and it would
not open. I found a simple registry fix which re-enabled their Classic
Control Panel.
Now I was able to change the contrast and brightness using the Classic
control panel but later when I went to revise my settings I found that I
could not open any control panel despite the registry fix still being in
place. I have posted the problem in the NVidia group but have not had a
solution.
I have tried uninstalling all drivers, then used a video card driver
cleaner and then finally removing all traces of NVidia (except NForce4 MB
drivers) and ATI drivers. I then using safe mode reinstalled the original
Inno3D driver from its CD but still the control panel will not open.
Now I have uninstalled all again and at this point noticed four default
monitor entries in device manager and in the registry which led me to make
this post.
I have disconnected the Hitachi and am trying to get the Samsung driver
installed from its CD. The display is presently in VGA mode which is
awkward but until I get the driver installed I cannot change it higher
presumably because I have mistakenly deleted one or more Windows default
monitor profiles. I have used sfc but as I only have an OEM SP1 recovery
disc plus SP3 I don't yet want to try a Windows repair.
I have been working with registry editing for many years and never had a
problem but this time maybe I have been too rash!
regards,
Beemer
