Issues With Quadro P2200 Drivers

[candygirl777]

I have a quad monitor setup, and recently purchased/installed a Quadro P2200 (to replace my GTX 770s, one of which died). The main problem I’m having is that on screen lock, or even logging off, after one minute instead of sleeping (as it used to do), it actually “disconnects” so when I move the mouse to wake it up, it has to reconnect again. I’ve already tried uninstalling and reinstalling drivers - and it initially worked as normal, but then reverted to disconnecting. After much research and tinkering, my partner and I figured out that the problem is with the drivers - specifically the Production Branch driver 471.68, which causes the display to power cycle reset and I nearly almost lost my local drive! The ‘New Feature’ driver works, except now I can’t get the NVIDIA Control Panel to open. Any help/suggestions would be greatly appreciated, thanks so much in advance!
