tried all three, no success.... Could this be PSU related? maybe i should buy a 1000 watt??
Only if you're running 3 S3's on the same PSU.
You can run two off of an 850 PSU. If you did another hard reset, changed your computer's IP address/subnet three times, then tried all three IPs I listed and can't ping the address in the DHCP table then my guess is you bricked it. You can contact Bitmain and get a new control board or get yours looked at for $25 if I remember right.
Another thought, it's not over 50c in your mining room, is it?
