Hi Redviper, I have a crappy MX4000 and had the same problem using Nvida newest driver 71.84
As per Skuzzy, "With the MX4xxxx card you need to be using the NVidia 61.77 drivers. Use DXDIAG to determine which driver you have loaded. The last 4 numbers shown in the driver version in DXDIAG is NVidia's version number."
I suugest that you get a free driver cleaner at "major geek.com" , remove all the drivers for video card and reinstall driver version 61.76 or 61.77.
They can be found at the Nvida website driver archive.
Hopes this will solve your problem.
