W7U/x64 + nVidia8500GT Random switching from Digital to analog
Hi everyone, New to the forums.
Everything was fine when I upgraded to Windows 7 Ultimate x64 until upgraded to latest nVidia driver for my 8500GT - the problem is that randomly every 10 to 40 minutes (varies greatly) there is an error sound and my monitor goes to power saving mode. If I then press the "source" button and switch to analog (both analog and DVI are connected to one monitor) then I can see whats going on but the resolution is all wrong. and it keeps switching back and forth between the two at random intervals - very annoying as you can imagine.
*I have tried rolling back the driver - same problem.
*I have tried completely removing the 8500GT from the device manager, restarting, and reinstalling it. Letting windows choose the most appropriate driver - Same problem occurs.
any suggestions would be highly appreciated!
Thanks in advance.
