Hi. I did read the other thread with exactly the same title, but the solution there didn't work for me.
I am running windowsXP and in the middle gaming the pc hung. I manually shut down, and when i started up the display settings were on 640x480 and on 4-bit res. Changing those and applying the changes doesn't work, it simply reverts to the low res.
The videocard is geforce 8400gs, and i did download and install the latest driver but still no joy. trying to get a driver for the Mitsubishi Diamond Plus 9l monitor now. I've been using these with no problems for a long time with Intel D945GCR and duo 2140 1.6
There is a yellow exclamation mark on the NVIDIA GeForce 8400 GS under display drivers in the Device Manager, and under properties it gives the message:
This device cannot start. (Code 10)
Any help would be appreciated!
