Diablo 3 is the only game booting up. Rest of the games just instantly stalls my pc.
Swarm stress test ran 1 time in CFX upon exit it stalled my pc and that was the only time it actually worked.
In MSI Afterburner the second GPU it shows 0% activity 0 degrees fixed 20% fan speed. AMD Overdrive on/off doens't make a difference at all.
GPU-Z shows CFX is enabled. ULPS is disabled.
Used 3 different CFX bridges.
I don't really know what to do anymore.
Am I missing something really simple?
