1st, please disconnect 1 of the hash PCB from the PCI-E power plug and try to operate with 2 hash PCB instead of 3. (If your S7 shuts down after a few minutes or not.) If the PSU was not strong enough, your 2 hash PCB method may let you keep mining without the unit being shut off or stop hashing in a few minutes.
If the above does not work, please try hashing with 1 hash PCB at a time. You may have a damaged hash PCB in the mix and it could be interrupting the other PCB to hash.
If none of the above works,
Please try updating to the newest firmware.
