UPDATE:

Since my last update I have changed my miner to neoscrypt-hsrminer, changed video TDRDelay to 10 seconds, moved all cards to new risers and moved 3 of the cards to my new DPS-1200 PSU. I was still having issues with windows freezing. Absolutely no change.


but wait, there's more.

After uninstalling my nvidia drivers and reinstalling using Windows 7 compatibility mode, the rig is finally showing improvement. I can actually leave it on all day with little to no human intervention. I still have a babysitter script that restarts hsrminer if the application closes (just in case) and a 3-hour reboot cycle on my wifi outlet. Hopefully I can ween the rig off of all my automated scripts and timers a little bit.
