Whenever I kill cgminer, the system crashes after a short while (usually around 10 seconds).
When I connect with teamviewer or logmein, the system crashes.
I have 6 290's running on a MSI Z77-G65 with dual PSUs, and the problems started when I switched to stronger PSUs. I have one Antec hcp 1300, one FSP aurum pro 1200 two Superflower 1000w, and the only combination that seemed to work stable (no crash) is the 2x 1000w Superflowers. That sucks, given that I go over 1150w for the primary PSU when maximizing hashrate, and they suck in terms of efficiency on 100% load.
What I tried so far:
Using Windows 8.1 built-in drivers only
Using ATI 13.12 drivers
Disabling cgwatcher so that cgminer doesn't have to provide API support
Using afterburner rather than cgminer to clock my cards
I'm stuck
