Well I was hoping the latest NVIDIA driver update (355.82) might finally fix my black-screening problem, but it appears to just be for game updates - Mad Max and Metal Gear Solid. I have purchased Mad Max, so want this update, but as soon as I try to download the game via Steam, my system black-screens within 5 minutes. Imagine trying to download 24.6GB of game in 5 minute increments, with a forced shut-down and reboot between each crash...
The only way round it at the moment is for me to remove all of the various NVIDIA driver elements on my system, run DDU (Guru Display Driver Remover) in Safe Mode to get all of the bits left behind after the Programs and Features uninstall, and then in NVIDIA driverless mode, run Steam and let the download complete, and then reinstall all the NVIDIA drivers. This does work, proving there's definitely an NVIDIA GPU driver issue, but none of the 20 to 30 tweaks I have found through trawling the 'net have worked so far. My system also crashes every time there is a Windows update (the download element, I guess) so you can imagine at the moment how often that is happening.
Soooo frustrating - I have pretty much given up actively trying to find a fix, and will now just have to monitor the various forums where the problem is being reported and hope a fix is eventually found.
