Precision M4400 Laptop Freezes, Screen Goes Blank, etc

I'm running Windows 10 32-bit on a Precision M4400. I purchased it with Windows 7 installed. After a while I had continual problems with BSOD. After doing a Google search and discovered the problem was the video driver. I reverted to an older driver and problem solved.

Now I've installed Windows 10 and having problems with freezing and the screen going blank. The fan speed always increases before this happens. I'm pretty sure my problems are related to the video driver again. I've tried changing the driver but Windows 10 keeps reverting to the latest driver. Any ideas how to resolve?
